    biscoff latte
    Elizabeth X.

    Was walking after my meal on a Saturday afternoon and stopped by Margin Cafe. Saw the Biscoff Latte and immediately wanted that. However I also saw a Butter Pecan Latte and was conflicted. The staff said their biscoff latte is their specialty so i decided to try that drink. It wasn't that sweet and it was bad. [[HIGHLIGHT]]Inside is very nice, around 5-6 tables and a couch, with some bar seats near the door and a few benches as well.[[ENDHIGHLIGHT]]

    [[HIGHLIGHT]]It is a cute coffee shop in diamond bar.[[ENDHIGHLIGHT]] Has a lot of unique drinks which I like. My husband got a horchata latte as he wanted a hot latte yet most of specialty drinks are not available in hot and I got a biscoff latte. We liked how the drinks were not too sweet but still had those unique flavors. It was our first time at the cafe and the person who worked there explained and recommended drinks for us which I was grateful for :) It is located in a plaza so there ate enough spaces for free parking

    [[HIGHLIGHT]]We came here for a quick morning study date and enjoyed the ambiance of the space - it was spacious, quiet but with nice music, and had lots of outlets to plug our laptops into.[[ENDHIGHLIGHT]] [[HIGHLIGHT]]The bathroom was also really clean![[ENDHIGHLIGHT]] The servers were nice and accommodating, serving us even though their payment systems were down (they don't take cash but thankfully the systems worked before we left so we were able to pay) We got some baked goods and ordered Biscoff Latte and Vienna Latte with cream top. Baked goods were solid and the drinks were yummy and well-concentrated, not watered/sugared down. Would love to come back for another study date here!

    This was my first time in Diamond Bar so I can't compare this spot to other shops in the area. However, I can compare to the coffee shops in LA. I got the Biscoff Latte and loved it!! They have whole milk and non dairy (no 2%). The latte was the perfect amount of sweet. The Biscoff flavor is there and not too overpowering. [[HIGHLIGHT]]There is a good amount of indoor and outdoor seating.[[ENDHIGHLIGHT]] [[HIGHLIGHT]]They have wifi as well.[[ENDHIGHLIGHT]] They have a sign that requests one drink per person if you're dining in. Also that if you are staying more than an hour, to order more drinks. Not sure how much this is enforced.

    This coffee cafe is located in a small plaza. I was in the area and stopped in for an iced drink on a near 100 degree afternoon. They have several outdoor tables (thanks, but not on this hot day!) and a dozen tables indoors. I ordered a Biscoff latte (only offered as an iced drink) and a slice of Biscoff cheesecake. The smiling young woman who took my order let me know she would bring it to my table when it was ready. It wasn't very busy but it took about 10 minutes for my order to be brought out. The Biscoff cake was really delicious. The Biscoff crust and sprinkles of crumbs on top were wonderful and the cheesecake was creamy, light, and slightly sweet. It has a whipped cream texture. I truly enjoyed this. The Biscoff latte was a bit of a disappointment. I could see it being made and a jar of Biscoff cookie butter was used as an ingredient (although I couldn't see how much). Oddly the latte visually looked like it had the cookie butter but there was no taste of Biscoff at all. The coffee flavor was very bold and was all I could taste. Fortunately, I really liked the taste of the iced latte even though the Biscoff flavor was completely absent - I still enjoyed it. I appreciated the signs they had up on the walls advising customers to be considerate and, if they were going to camp out with their laptops in the shop, to please, at least buy a second drink. It appeared to be effective as there were plenty of tables available for paying customers. 3.5 stars rounded up.

    Fantastic cafe!! I searched coffee places near Diamond Bar and I selected this cafe for an early morning talk with my friend. I ordered an iced Blueberry Latte with soy milk and my friend ordered their Coconut Latte. Drinks came out fast and arrived on a cute small tray. There was plenty of seating. We had a great time catching up. The interior was beautiful and they even had a restroom! My drink was so delicious, it tasted like a blueberry muffin, but with espresso! I really enjoyed my time here, I can't wait to come back!

    A friend of mine had posted about this cafe and I've never known about it! Easily overlooked and definitely a gem. The owners are very friendly and willing to educate about coffee and their drinks. The Biscoff latte is unique and not overbearing. Plenty of indoor seating as well as some outdoor seating. Will definitely drop by more time allowing as it's in a convenient location. The interior is very cozy and well decorated. Good to enjoy coffee and do some work or read a book. Great place to relax and enjoy some good coffee.

    Came to this spot to do some work with my friend and it was a nice spot for a good cup of coffee and pastry. [[HIGHLIGHT]]The seating was also quite comfy, I'm kind of a chair snob and hate when coffee spots have chairs that leave marks on your legs.[[ENDHIGHLIGHT]] The butter pecan iced coffee was pretty yummy as well!

    I've been coming here since they first opened and really enjoyed their coffee, drinks, and pastries. It's a cute coffee house with good amount of seating both indoors and outdoors. It's located in a plaza with lots of parking. This time I ordered the mango matcha (seasonal item), and it was A.Mazing! The mango puree was fresh and not too sweet. It paired so well with the matcha (which I have never had)! Both the Nutella and almond croissants were yummy I definitely recommend this place.

    I might be the minority here but I wasn't impressed with Margjn. I ordered the black sesame latte and the black sesame croissant. The croissant seemed days old even after it had been warmed and the latte was very underwhelming in flavor. I may try to visit again and order different offerings.

    Coconut Latte w/ Oat Milk.

    A great coffee shop with quick and friendly service! I've come by to Margin Cafe a few times during a needed break time and place to chill to do some work on the computer. The cafe has adequate indoor and outdoor seating and plenty of parking spaces nearby. The few times I've come here there are usually customers already working or studying at the tables. It's very quiet and you can get plenty of studying or work done in peace. FYI, the location offers free WiFi for 90 minutes with one purchase minimum if you plan on staying. I've ordered a Coconut latte and Matcha latte during my few visits. The drinks were tremendous. The drinks were prepared quickly and I had no complaints. I've been drinking matcha lately and theirs was excellent. I'd bookmark Margin Cafe if you want a nice place to have a cup of coffee or study in Diamond Bar!

    Rose petal latte
    Silver P.

    So far I love this cafe, a husband and wife coffee shop that gets their beans roasted locally and bake their own cakes Got their standard ice coffee and it's more of a darker roast which is perfect for milk additions. Currently tried their seasonal drink, the rose petal latte and it's not too sweet and perfect! Their jalapeño croissant is delicious and I also love that they're pet friendly. (Cats too!) Such a cozy cafe and the service is so calming and friendly. They also do collabs so I'll be looking forward to coming here again!

    Margin Cafe Coffee Roasters is located in Towne Centre Village in Diamond Bar in between Smoke Shop and Nails & Spa. They have lattes, blended frappes, smoothies, traditional coffee, tea, and refreshers. They also have seasonal drinks. Margin Cafe has become one of my favorite coffee shops. Their Biscoff Latte is my go-to drink. It's served iced by default. Excellent latte! Perfect blend of biscoff flavor, espresso, and milk. Service is pretty good. I'm usually greeted upon entry otherwise I'd be greeted at the counter. The baristas are warm and friendly. Drinks usually arrive within a few minutes. There's a lot of tables inside and some seating outside. Usually it's packed with people on laptops. Occasionally, there would be some loud conversations. I absolutely love their Biscoff Latte. I'm always back for more!

    Do they close early on Saturdays? I'm here now and Yelp says they close at 5pm but it's closed now -_-

    Closed on Saturdays? Bummer?

    Only this weekend. We have to attend a memorial service of our family. We apologize for any inconveniences caused.

    Are there outlets available?

    Yes but it's limited.

    How does the painting option work?

    Painting package includes all material and supply, and a free refill on your drink. 2hr package is $38/person or $68/2 people.

Slightly sour, but fruity coffee. Overall, I enjoyed it. Good mouthfeel too. Good temperature, it wasn't too hot nor luke warm. MANGO MATCHA At first taste, it tasted more like guava. But it was indeed mango. But a fake mango flavor. The mango flavor was there, but could not taste the matcha. It wasn't bad, but I had better mango matchas elsewhere. CUSTOMER SERVICE It was okay. Not bad, but not great. Staff could smile more than just stare at you. Even say "Hello" or "Welcome" when you walk in the coffee shop. LOCATION Located in a small strip mall at Golden Springs Plaza. Parking is medium-sized for the amount of businesses here. I had no issues finding parking in front of the coffee shop, although more and more parking spots were being taken. AMBIANCE + SEATS The ambiance was relaxing. No loud music. Lots of people coming in and working on their laptops. Five small tables for two in the center. Along the wall there were bar seats for 19-20 people. There's a long communal table in the center for seats for 4-5 people. At the front and to the side, there were 3 tables for two. Outdoor tables for two right outside the cafe. Bathroom is outside of the cafe and you have to enter the other part of the building with a bathroom code to unlock. Will I visit again? Maybe if I'm in the area. But I'm in no rush to come back.

You can find parking on the street, or you can park in the lot. There isn't a parking meter anymore, so I'm not sure what the city guidelines are for payment, but your first two hours parking there are free! When walking towards the cafe, you will see a sign for a pub. You can walk inside and turn towards the right. The cafe and baristas are located towards the very back! Yet, once you go inside, you notice all the seating that is available. We have asked towards the baristas, and used a little tablet to scan their menu. We ended up ordering a tonic and a banana cold brew. They also had food items! We had chosen their breakfast burrito. Their coffee is strong and you can feel the caffeine. Yet, the sweetness is perfect and can mask your actual caffeine intake! It's amazing how they can do both. Their burrito was very savory and delicious as well. It's always quick and clean at this cafe. The baristas are always sweet. My fiancé and I do come here to do work, and their WiFi is decent, too. I highly recommend this cafe if you're ever in the area!

This one is just a Coffee Lab, so it doesn't have the extensive baked goods like the Cerritos location, but still has a decent selection towards the cashier area. Some refrigerated chubby cakes and slices, canned and bottled drinks, and then some pre-wrapped baked goods like bread, cookies, mochi, etc. They can warm it for you too I believe. With the increase of Smoking Tigers, I heard from my friend that also frequents these that they're cutting a lot from their menu, food and drink wise. My beloved choco mugwort, please return as a seasonal drink at least. Staff is super friendly and helpful. I was on the fence about ordering a limited seasonal Yakult cold brew style drink but feared that it was going to be more sour than a standard Yakult because of the cold brew and after explaining the flavor profile thoroughly, I opted for a safer drink that I've had before. Their banana milk latte. I'm a caffeine addict and this was a good pick me up. Not super strong and didn't zute me immediately, but this is perfect for those slow release caffeine people who like to sip on their drinks. Perfect banana milk taste after mixing and a perfect coffee for me, not too bitter or sour lol. There's outlets at the tables near the window and lots of places to sit down and hang out. Plenty of parking but it can get busy since a lot of people are in the plaza to go to 99 Ranch or the other businesses (restaurants, shopping, tea, etc.) but also everyone hates parking at the plaza across the street so they're parking here and walking over haha... It's insane this used to be a Diamond Bakery. They've existed since the 70's and 80's and there's only 2 left in existence (Vegas and MPK). Really makes you think of the passage of time. ANYWAYS, there's a point system if you sign up with your phone number and an app where you can access deals, order ahead of time, send gifts, and they have special days each month!
