Grid Coffee is wedged between two other buildings (peep my photo)! Located in Diamond Bar, Grid Coffee brings aesthetics, good intentions, and good vibes. I had stopped by because I wanted to get a croffle for myself. Of course, trying their coffee was also on my to do list. We stopped by on a Sunday morning, and quickly got to place our order. My fiancé ordered their tonic and of course, I ordered their Banana Cream Latte. I also scored their last plain croffle of the day and also got their everything seasoning croffle. It didn't take long for us to get our coffee or our pastry. Their plain croffle was good, but I wished we had the option to have it warmed up. Their everything seasoned croffle was decent if you want a savory pastry. My banana cream latte was strong, but wasn't strong in banana flavoring. I mixed my cream too towards the bottom, and still found barely taste it. The baristas here are also very aesthetic and silly. They had a great time making coffee and taking orders. The art here is stunning. There's also plenty of study space with cushioning available. It's a lovely concept. I think I'll have to come back to try a different drink.
Coffee shop with matchas and cold brew. Came here to catch up with a friend and ordered a double matcha latte, which had both matcha as well as a matcha cream top. I split a Nutella croissant on the side as well. The croissant was a tad stale and there was limited Nutella but I did really like my drink. There's indoor as well as outdoor seating. Some people were working in the cafe and there was WiFi. There's a free parking lot. Credit cards and Apple Pay accepted.
Solid cafe with decent matcha and hojicha drinks but the matcha here is on the lighter and slightly sweeter side! This is a popular study place but there's limited seating and limited outlets but WiFi is good and the bathroom is clean! Tip: There's lots of parking! Also card payments only!
I am really liking this place for some specialty matcha drinks. This might be my new goto drink place in Diamond Bar that has so so many coffee places. 2 visits and so far great service and great drinks. I like the vibe when you come inside, it's got that industrial feel, roomy, cool, not hot. Very enjoyable
Very mid coffee. I wish the espresso to milk ratio was balanced. Felt very creamy/milky! This was my second time trying it so wanted to give it another go :/
I had a good experience at Grid Coffee (Diamond Bar). I ordered the Madagascar Vanilla Caffe Latte ($7 - Large - Iced). It's three shots of espresso, milk, and Madagascar vanilla syrup. I felt awake after sipping. It's TASTY, fresh coffee! (Important: Cash is not accepted. Bring Card or Contactless Payment.) I arrived at Grid Coffee (Diamond Bar) on Thursday (around 9:17AM). Parking is easy. The lot is spacious and big. However, this business has awful visibility; it's very easy for new guests to overlook it. But like a strongly guarded secret, this business is POPULAR. Staff is efficient and amicable. Staff is polite and knowledgeable, but Staff is also curt and very focused on crafting their coffee. My coffee took four minutes and 26 seconds. As mentioned, I ordered the Madagascar Vanilla Caffe Latte ($7 - Large - Iced). When thoroughly stirred, the coffee's true flavor blossoms. The potency becomes balanced, and the taste of vanilla & roasted coffee lithely intertwine. The aftertaste is reminiscent of a smoky caramel. There's utility and personality in this freshly brewed coffee. It's easy to understand why this spot is so popular. On ambiance, Grid Coffee (Diamond Bar) is a study/work paradise. Unlike the tiny outside, the interior is unexpectedly spacious. There's about six electrical outlets. There's also customer internet with password; details are in small text on the counter's menu. The location also has about four tables, one long wooden table, and five mini portable tables. In addition, Grid Coffee (Diamond Bar) is clean, well-maintained, and well-ventilated. There's a gender neutral restroom in the back, and the music is chill & calm. The location is filled with working college students whispering about Harvard and preparing for the future. Overall, I found unexpected joy at Grid Coffee (Diamond Bar). The coffee is affordable, good quality, and functional. The location is comfortable and calm. If searching for a wonderful study/work spot, this is a very easy recommendation. 4.8 out of 5!
This place was super yummy! There was adequate space for sitting to either chat with friends, study, or work. I ordered the mango Matcha and the banana Matcha Latte, and both were delicious. They were sweet, creamy, and had a rich matcha flavor without being overpowering. The staff were super friendly, and once I ordered, the drinks came out quickly. I'll definitely be back!
Tried Grid Coffee in Diamond Bar for a quick drink and pastry run. * Double Pistachio Latte: The pistachio foam on top was creamy and rich. We ordered it with soy milk, but the latte base tasted a little watery compared to the rich foam. * Matcha Croffle: Crispy and flaky hybrid pastry. The matcha side was rich and tasty, though fairly sweet, while the plain half tasted like a regular waffle. A solid spot to visit if you enjoy creative specialty drinks !
Coffee and matcha: 10/5 -creamy, rich, not too sweet Service great -coffee gets made fast Vibes good - good for studying, seating got cushions now Come here at least one every week
Very Disappointed I used to really like this place. I loved the industrial-style atmosphere, and it always felt like a cool spot to sit down, relax, and enjoy a freshly made specialty coffee. That's why I was honestly shocked by what I saw during my last visit. I came in one morning with a friend, and I watched the employee take pre-mixed coffee that had already been prepared and simply pour it into a cup with milk. There was no fresh grinding, no espresso being pulled, and no coffee being made to order in front of us. I paid nearly $7 for the drink, expecting a freshly prepared specialty coffee. Instead, the preparation looked more like a pre-made/instant coffee process. For a coffee shop charging specialty-coffee prices, this was extremely disappointing and felt very misleading. The atmosphere is nice, but for me, the quality and preparation of the coffee matter much more. After seeing this, I definitely won't be coming back.
I've had mixed feelings about this place. I used to think it was just okay, but last time I went I had a blueberry specialty coffee drink and actually really enjoyed it. Their matcha is okay, but I think their coffee is great here. Just be warned, they are typically understaffed, and the wait can be long, I think a lot of it comes from big group orders. They do have very unique seating though.
Came in on a Thursday at 1pm. Most of the seating was taken and seems like thjs place is laptop friendly. The ambiance is more on the trendy side, with wooden but tasteful seating, art hanging on the walls and a unique chair in the corner for what seems to be a photo-op. I ordered the iced cream top hojicha latte and my drink was ready in less than 3 minutes. It was so fast, I'm not even sure if they make the mix hojicha powder on the spot or if it's pre-made. Regardless, the drink was tasty and well made. This ran me $7 ($8 if with oat milk) and tipping optional. Grid Coffee is one of the better coffee/matcha/hojicha spots in the Walnut/Diamond Bar/Pomona/Rowland Heights area
First time I came here I thought the latte I got was just ok. Wanted to try a different flavor and saw they had a cookie butter latte. I was pleasantly surprised at how good this tasted! The cookie butter foam was so good and matched perfectly with their coffee! This will be my new go to latte for a while!
Stopped by to get some homework done. Very cute, minimalistic coffee shop with plenty of seatings and plenty of outlets from what I saw. Really great spot to come study or get work done. Ordered an iced vanilla latte with oat milk and it was delicious. Wish I got to try their food but wasn't too hungry yet. Very chill settting. Will return when I'm in the area read more
Haven't been here for yeaaaars. First drink I got was either the Dalgona milk tea or Dalgona latte and it left an impression! Decided to try their lavender latte -- light and refreshing. Not a place I'd sit and do work at but I can count on a quality drink here. 4.8 overall! read more

I stopped by the merchant café so that I could have coffee with a friend. It is in the plaza with the Jack in the box, across the street from Walmart. One of the nice things about this place and why we picked it was because they are dog friendly. My friend has a very team dog, and they were able to bring their dog inside the café. No problem! It had an industrial look - very modern. Two regular sized drinks same out to about $15 with tip. I was excited to try the Blue lavender Matcha latte. I am not sure why it is blue lavender. It definitely didn't affect the color. The matcha was dominate and it was green. It tasted pretty good. It was a little on the sweet side, but was still good. I would recommend here again!!! read more

Tried their Matcha Caffe Latte and it has a perfect amount of bitterness with the taste of espresso! There's plenty of seating inside to study, yap, and work. The drinks came out fast and did not have to wait long! read more
Love, love this place. It's both a curse and a blessing that my work is so close because I have to stop myself from coming here everyday as soon as I'm off the clock. Favorite drinks are the Einspanner Latte and Matcha Cream Latte. What they both have in common is their delightfully indulgent and thick cream they layer on top of these drinks that elevate the drinks so much. Aside from not the most comfy seating which at least still add to the aesthetic, the vibes here are great for a good book and the music is always on point. read more

My go to coffee spot of all time. Their coffee is pretty strong. My favorite is biscoff cream latte. The service is quick, the cafe is quiet and has a chill vibe. read more
Grid is in a plaza with plenty of parking. The ambiance is super simple but inviting. Plenty of people were inside either chatting it up or on their laptops. My son had to use the restroom which is located in the back but he walked out quickly because it wasn't stocked with seat covers or toilet paper, which is a total must for me to give 5 stars. I ordered the Einspanner Latte. Customer service was cool, easy to speak to. My latte came out fairly quickly and tasted good. read more

I came here multiple times and earned points where it told me I can redeem a free drink. Staff told me they don't accept anything like this which is ridiculous. Why have a point system and offer this when you're not going to accept it? Very confusing and service from staff were not kind. read more
This place was petite and a good place to hang out with friends. I had the grapefruit matcha latte, which the grapefruit ads a nice flavor to the coffee. I didn't taste much matcha in there. The service was great with friendly staffs. read more

Even after Gavin Newsom declared state of emergency in socal with its life threatening storms/floods, it's crazy how we stumbled upon this shop. The freeway was a diff story with the amount of water lurking. I tell you this though, the coffee is good to my surprise. We ordered the Dalgona and the Einspanner and both were good, but the Dalgona was a home run if I do say so myself. The honeycomb drenched and coated with the liquid added sweetness to it. The Einspanner tasted good and the foam lol sweet. Excellent. Presentation was nice too. Vibe is nothing, but minimalist. The aesthetic profound in simplicity and homey. Some people were studying there too. Maybe the wooden chair was comfortable, lol. Regardless, people come thru. read more

Einspanner latte is very strong and usually on the bitter side. I think they used stereoscope coffee bean so it always tasted really good. Their croffle is amazing too! read more

was in really good spirits! decided to stop by and finally try this cafe since i was in the area. there's lots of parking, which is a plus for sure. it was already brunch hour, so there was a good amount of people. luckily there was enough seating and everyone seemed to have their drinks, so i thought it would be fairly quick as i was the only one about to order. i wish they had another hard copy of the menu to browse, they have only one and it's by the register. but i had looked online beforehand and already knew what i wanted! there was a customer at the register who was talking to the barista for a few minutes. i think they were friends (which i totally adore), but a minute or two went by before they noticed i was there. i could've said something but i didn't want to interrupt, they could be catching up for all i know! i tend to think optimistically lol finally i'm about to order but felt really rushed. i ordered and sat on the side, where the friend comes back to the bar and is talking to both baristas at the same time. again, i didn't mind at all, they could be friends yapping it up! however, they hadn't started my drink until about 5 mins later, when i hear a barista say "ugh hold on lemme make this drink real quick". she makes my drink in less than a minute (turns out quick service is possible apparently!) and go back to talking. when they hand my drink on the bar, it had been about 10 minutes by this point, with no acknowledgement as i get my drink. maybe they have good service based on other reviews, but my experience service-wise was okay. as for the drink itself, it was between the range of okay/good! i ordered the double matcha. the foam was definitely the star, it was just the right amount of sweet. however, the matcha was just okay. i've had worse but i've had better also. i ordered the small so i got less ice which makes sense, but i swear it had like 4 cubes because by about 15 minutes later there was literally no ice. obviously it's expected when it's 95 outside, but a couple more cubes would've been nice yk? overall, this place has potential. i felt like i was interrupting (my mistake for ordering during business hours lol) and the drink was alright. i can check this place off list of matcha places to try at least! read more

Second time I've visited and haven't been disappointed! I got the Einspanner Latte which had a good coffee flavor with a lightly sweetened and creamy foam top. The inside of the cafe is very minimalistic and aesthetic, but there aren't many tables. It's mostly benches and chairs. The wait can be awhile so don't expect to be in and out super quick. A solid coffee spot around this area! read more

Loved the interior design and the music selection. Very clean and tidy space. Baristas are friendly and quick. The Spanish latte is my go-to. Tried their pastries today they didn't disappoint. Went for a quick trip during lunch, everything was smooth and seamless. read more

One of my top local favs to grab coffee! I usually grab an Einspanner here, it's a joyous medley for your mouth! 10/10 I've been on a matcha kick, so trying the Matcha Cream was on my radar. Don't get confused bc they have both a Matcha Cream and Matcha Cream Latte. I rate it 7/10! The cream they added was great consistency giving the full drink smooth and milkyness, however I was just disappointed that the Matcha flavor didn't pull thru as I expected. I was wanting more flavor thinking it was just the cream being added and no other dilution from milk or so. It's good, but I wouldn't say it's the best that I've had. I'll maybe try their matcha latte next! All in all, still love this place and glad we can have a near coffee spot locally that isn't a traffic jam ways away! read more
If you're near Diamond Bar and you love both passion fruit and espresso tonics, you have to try Grid Coffee's iced Passion Tonic Coffee ($6). Under the espresso section of their Drink it menu, I felt like it also could have been named a Passion Espresso Tonic, rather than a Passion Tonic Coffee, but maybe that's just me. It's made by combining a passion fruit purée base, lemon juice, fun, and a sparkling americano over ice. For the espresso, it's a double origin, half Brazilian & half Guatemalan, from Stereoscope Coffee roasters. Grid is in a shopping center where they have ample parking in the free lot out front. Even though it looks very narrow from the outside, it's very open inside with some seating options, and minimalistic art on the walls. While we didn't get any pasties this visit, the waffles seem very popular with the other patrons. They have a restroom, and the staff was very nice and they handled the seemingly constant rush with grace. read more

The matcha lemonade didn't have a super strong lemonade flavor which is great. Matcha was the dominating flavor, which indicates to me that it was good matcha and most likely a homemade lemonade with a lot less sugar than most lemonades. The service was good. The ambiance of the location is definitely more unique. More open space and not much traditional table space. It reminded me of those giant wooden benches that are stacked on each other in-between escalators in some malls read more
A tucked away spot in Diamond Bar. I tried the Dalgona Latte as I have a little bit of a sweet tooth. The first sip isn't as sweet as I liked but as it melts it, the sweetness is perfect. The atmosphere is very chill, seemingly a good place to read or book, study or take care of those annoying work tasks. Very photogenic and clean or as influencers call it these days "aesthetic." Highly recommend if you are looking to get away from your large chain coffee stores. Looking forward to trying more in the near future. read more

Came here on a whim meeting a friend. Very different type of concept no visible menu.. the place was pretty busy and a nice line, but move fairly quickly. I ordered an ice herbal tea with no sugar or sweetener. It was tasty, but somehow the teabag broke all the leaves and herbs covered my drink, which made it undrinkable without getting a mouthful of the ingredients not my favorite. I couldn't even finish or enjoy my drink. read more
Service was quick and workers were helpful but I really dislike the ambiance of this place. It's nice in a "take cute cafe photos of yourself with a drink" type of way but not a "sit there and catch up with your friends" or study there type of way. It feels very cold and not home-y. Although the Strawberry Matcha Croissant had been sitting out and therefore wasn't warm or crispy, the flavor of the matcha with the freeze dried strawberries was enough for me to enjoy it and finish the whole thing. I also got a caffe latte and a matcha drink for a friend. The latte was good, not great, but after sipping my friend's drink, I can see the matcha quality is good. read more

I have been wanting to come here for a while so I decided to try it out. The interior of this cafe is so cool. It has a nice minimalist/ gallery vibe. I enjoyed the wood benches they have, I just wish there were more cushions. They were also playing pretty good music. I ordered the Blue Lavender Latte. It was delicious. The lavender flavor didn't overpower the rest of the drink. It was a nice, sweet latte. read more

Yummy food! Came in here to work and was really laid back. The seating is cool and the drinks are yummy. Paid about $20 for my drink and toast. A little pricey but within range. read more
I almost couldn't find this place. I felt blinded searching for this place. It was in between the market and the place with the patio seating outside. For some odd reasons, I drove past it. Lol place looked small and narrow from the outside, but it was so spacious on the inside. ANYWAY, I came here because I wanted to try the grapefruit caffe latte. I also wanted to get the Einspanner but ended up with just one drink with a lavender cookie. The latte was refreshing. If you're looking for something not so strong and not so creamy, then this is for you. Honestly, the latte tasted good because of the grapefruit lol without it, I don't even think I will be interested in it at all. If in the area, I will get the Einspanner. The lavender cookie tasted a bit dry and weird at first. Probably because I m not a big fan of lavender. Don't ask me why I got it then...it was a pricey cookie, so i didn't want to toss it away after one bite, so I took a 2nd, then a 3rd bite. It turned out not so bad. I dunno if it was because of the white chocolate, but it got better and better after each bite. Guess I got used to the lavender flavor. Overall, this place is decent with decent drinks. Good looking people working there : ) read more

Blueberry Cafe Latte (4/5): - Great drink! Chia seeds were mixed in with the blueberry syrup and I loved it! The blueberry flavor mixed in well with the latte. - One downside is that I did not like the whole blueberries in it. Whenever I bit into the blueberries, the sour & frozen flavor overpowered the drink. - Personally, this would be a 10/10 if the blueberries were blended into a puree. Cold brew (3.5/5) - not a fan of sour cold brew. Interior - Good place to study, but seating is limited. - Has good lighting. Service - Everyone was really nice read more

We came here on a Saturday around 9AM and it was pretty empty. My friends and I got the matcha cafe latte and the strawberry cafe latte. I really liked the strawberry latte since it was a perfect blend of coffee and strawberry flavors. The matcha latte was pretty interesting since the matcha flavor wasn't too strong. There is plenty of parking in this plaza and I would definitely come back to study here in the future. read more
Introduction: I stumbled upon this establishment after lunch while trying to find a coffee shop where I can get some work done. Drink: I tried their Einspanner latte, Kyoto Cold Brew Latte, and Dalgona Caffee Latte. Amongst the three, the Einspanner latte is my favorite and I will explain why: Kyoto Cold Brew Latte: In terms of Kyoto Cold Brew Latte, the base, the Kyoto Cold Brew, has good relative strength but with the addition of dairy, the drink overall becomes generic tasting: it's not a bad cup of coffee but there aren't any unique aspects I would personally go out of my way for. Dalgona Caffee Latte: The Dalgona Caffee Latte is best suited for those with a sweet-tooth: it's essentially latte with the additions of Dalgona honeycombs that slowly dissolves into the coffee with the passage of time. With each sip one does get a slight sugar rush. This coffee essentially is just sweet but it lacks character and depth for me personally. Einspanner latte: The Einspanner latte, now this is the latte that wins me over and makes me come back to Grid Coffee. Think of the Einspanner latte as a mature version of the Cortado and Piccolo latte; it is smooth, bears depth, complexity, and lightly rich due to the cream that's included with the latte: the cream is what makes the latte taste unique and stand out. Ambiance: Contemporary, minimalistic Service: The staffs are all polite and friendly. Price: Affordable read more

My new go-to spot to get my Matcha fix. I always order the "Blue Lavender Matcha Latte" over ice with Oat Milk. It is very creamy, aromatic, and has just the right amount of sweetness. Moreover, the staff is very kind and helpful in providing recommendations. read more
Grid coffee. With the high reviews and nice looking drinks I was excited to try. Got the blueberry lavender latte. Since this was the only drink they said that they make syrups in house for. Too much Lavender flavor for me. Was not balanced enough. Worse part was the girl in front. Helped me and was too busy to answer questions and I couldn't really understand her cause she wasn't giving us attention. Being my first time I wanted better service . read more

Is this a good place to study?
Depends, if you have many books and need space, they only have one long table that could be most comfortable for that. I've seen a few people study there the times I've come and they've utilized the table. They have two other seating arrangements…
Do they make their own coffee? If so, do they sell the beans at the store?
Do they have outdoor seating for people with dogs or are dogs allowed?
Yes they do! For both questions. I have brought my dog here several times.
Does the matcha powder used have sugar in it?
Yes, it does! They said it is pre-sweetened. I always order a strawberry matcha latte and you can choose to have less strawberry or matcha to make it less sweet.
What is the einspanner?
Viennese coffee with a lot of whipped cream on top. Typically drunk through the cream, without mixing.
