Matcha Cloud 9 and Cloud 9
Vincent P.

Decent Korean coffee shop at The Source OC but it didn't have anything special that would make me want to come back. Friendly service and they have outdoor seating as well. I got the Cloud 9, which is their latte with a cream top. It tasted alright and did its job as a coffee fix, but again, nothing noteworthy. Since there's so many coffee shops to try in the area, I wouldn't come back here, but it's a reliable option if you're in need of coffee at The Source OC.

Banana Latte
Vince V.

This place has lots of seating. This is a crowded coffee house with a good vibe full of people working or completing their studies. A notice wonderful aroma of the beautifully creamed drinks. This place is located in The Source, so after you have coffee you can go shop, browse or check out food you may want to eat soon or later. Lots of parking of course, because it is in The Source. One day, I want to come here, after or the day after a 10+ mile distance, 2000+ foot elevation hike; to enjoy coffee and vibe, learn Korean speaking while teaching Spanish in return, and reward myself.

Hojicha latte
Melody T.

Every time I come to Buena Park, in-sit is a must visit. I got the Hojicha latte which was a little too grainy for me this time. But in the same day that night I picked up a hot London fog and it was delicious. The people there are really nice and if you dine in, they go and find you to give you your drink or food. Super chill inside! I saw people studying or just chatting.

In-sit coffee I stop by every time I go to Buena Park in Orange County. I really love their affogato and coffee -- both are excellent. They have both indoor and outdoor seating, and any spot is nice. One small downside is that there's no restroom inside the café, so you have to use the public restroom outside. However, the public restroom is clean and kind of spacious, which is a plus.

Been coming to In Sit Coffee for the last couple of months and it's easily become one of my main study spots. The matcha and coffee are consistently great and reasonably priced, which is honestly a win when you're spending hours here. The ambiance is cozy and relaxed. The kind of place where you can really lock in and get work done without feeling rushed. When the weather's nice, the patio is a huge plus. There are plenty of tables outside, making it easy to switch up the scenery while still staying productive. In Sit Coffee will always have a soft spot for me. It's one of the very first study spots I found when starting my school program, and it's been a reliable go-to ever since.

Hazelnut latte
Vera L.

Busy coffeeshop on a Friday evening after dinner. It's located upstairs at The Source plaza with free structured parking. I love strong coffee and this place had great lattes! I tried their banana and hazelnut lattes and both were very good. Love that it's not too sweet or milky. Their pastries look yummy too!

I'm a coffeeholic and sometimes I need a coffee fix in the evening. However, it's hard to find coffee spots that are open passed 7/8pm. Luckily for me, I found a spot that closes at 10pm. In- sit Coffee is located in. Buena Park within a busy and lively shopping center. It offers a "relaxing and inviting atmosphere". You know this is to be true as every seat, both inside and outside) was occupied. There were lots of folks on their computers getting work done. Don't expect just coffee and drinks here; if your tummy is rumbling, they have several different food options. They even have a brunch menu available until 4pm. As for my experience, I just had a late night coffee. I went with my usual, iced vanilla latte. It was very good and I was lucky enough to grab a chair outside. The workers were super friendly and very nice.

Honey Latte
Arturo P.

I've seen a couple videos for this place! It is a very decent spot for coffee on the third floor at the Source! Service was quick and my drink was made pretty fast. However, it was pretty inside and outside, so there wasn't a lot of available seating, so we ended up walking around, which wasn't bad! The coffee was creamy and a bit strong, but I like that!

Came here on a weekday and seems to be a popular spot but plenty of seating still available. Interior is nice with exterior seating. Asked the barista for recommendations and gave a wide variety. I asked if they were more well known for coffee or tea and said it was a mix of everything...so we just opted for coffee since it's in the shop name. Vanilla latte was good and had the perfect level of bitterness. I personally don't like my coffee too sweet but if you're a sweet tooth I recommend you ask for more.

Latte, Hojicha latte
Iris Y.

Service here is really good, from ordering to picking up drinks. They really take their time with you and give you recommendations if you're struggling to pick a drink or food item. The cafe is also a good study spot, I saw a bunch of people with laptops working! Their tables are clean and there are no weird smells here. I got a hojicha latte with oat milk and my bf got a regular latte with half&half. My hojicha was really well made- the flavor was super strong which I loved! The only thing was that it was a bit grainy, but I always expect that with cold drinks. Overall the flavor and taste was a 10/10 and I'd come back anytime for this!

This Korean coffee shop hits you right away with that deep, roasted bean aroma--the kind that fills the entire space as soon as you walk in. Located inside a Korean shopping complex with various stores and a theater, it's super convenient and easy to stop by before or after shopping or a movie. The café itself is very spacious, with plenty of seating both indoors and outdoors, making it a comfortable place to sit and relax. Service is friendly and welcoming, though some staff members seem new, so things can move a bit slowly at times--just something to keep in mind. The bottled French drinks were okay but leaned on the sweeter and thicker side for my taste. The coffee, however, was solid and well-made, especially if you enjoy a strong, roasted bean flavor. Overall, a nice spot to enjoy coffee in a lively Korean complex atmosphere.

Located at The Source + easy parking + very relaxing ambience making it a good study spot or to catch up with friends. I got the summer peach ($5.50) this time around which was not good... my usual go-to is their maple chai latte.

iced sweet hochija latte and hot ceremonial matcha
Yiping K.

Parking: plenty of spots to park in The Source OC mall structure Vibe: modern, spacious, lots of seating, and well lit Drinks: hot ceremonial matcha not sweetened so matcha flavor was there and sweet hojicha latte had good roasted tea flavor Service: barista helpful in suggestion between iced/hot when unsure and drinks were made very quickly without a long line in the evening Other: open until 10pm which is perfect for dessert, plenty of seating inside, and want to come back for the seasonal cakes which were sold out at the time of my visit

We gave Coffee & a try, the coffee was excellent and provided just the right caffeine boost we needed. I ordered the Cold Brew Latte, which featured New Orleans cold brew concentrate. I swapped out the agave syrup for honey and chose almond milk for my drink, which cost $6.80. The caffeine hit was perfect, and I really enjoyed the flavor. Next time, I might opt for less milk or just stick with the cold brew and honey for a bolder taste. My friend chose the Brown Sugar Oat Shaken, a delightful mix of double shot espresso, brown sugar, vanilla syrup, shaken with oat milk (iced only), also priced at $6.80. She loved her drink and said it would be her go to choice for future visits. Overall, Coffee & is a fantastic spot for a caffeine fix.

No outdoor seating. Clean functional minimal decor. Staff wise not really friendly, just engaged with each other and there was no energy or enthusiasm Tried the banana pistachio bread warm up and maple cinnamon cold brew latte Honestly was not impressed. The bread was dry and stale. The drink itself had a lot of ice in it that made the drink taste watered down. Probably would not return overall with service and quality of food and drink.

I sat at the one available table and savored both items. The Biscoff latte was iced, with just enough ice to make it cold. I appreciate that they didn't overdo the ice like most coffee places. The flavor of cookie butter was vivid, sweet, and delicious. The cream top and crumbles of Biscoff added to the visual appeal. The lemon bar was slightly sweet and citrusy, with a tasty thin outer crust, the top of which was sprinkled with powdered sugar. For me, this was a perfect lemon bar in every way. If I lived anywhere near here, this would be a regular stop.

The place inside is cute with a clean, minimal vibe. There are small white tables lined along the wall with a bench and stools and some simple decor and artwork that gives it a cozy feel. It's not very big, but there were still plenty of open tables which was nice. Everything was clean and parking was easy since it's in a shopping center. I'm looking forward to trying more next time. Deff a decent spot if you're in the area and want something simple and low key.

Unfortunately, that turned into over an hour--with no updates from staff during that time. What made it worse was that we only found out after we had already paid that the kitchen was backed up. That's something customers deserve to know upfront so they can decide whether they're willing to wait. We were also there with a baby who needed to go down for a nap, which made the long, unexpected delay even more difficult. On top of that, they had already run out of matcha and the menu was extremely limited, which was disappointing considering that's one of the main draws of a place like this. Overall, poor communication and lack of transparency really ruined the experience. I understand delays happen, but being upfront and managing expectations would have made a huge difference. Extremely disappointed. We went to this place a long time ago when they first opened and remembered them having a more extensive menu and it being far better. Sad to see that this place has gone downhill. My family and I will definitely not be coming back again.

I'm ngl I'm pretty bummed out about that. My boyfriend and I were basically regulars here. I'm glad I got to see this place one last time before they temporarily closed. I'm hoping things don't change too much but hey, I'm up for trying whatever the plan may be for this place. We ordered a Citrus Summer and a Yuzu Tonic. As always, it did NOT disappoint. That Citrus Summer was probably the best I've had haha The place is always calm, quiet, and welcoming. It's a great spot to relax and get a drink at. I can't wait to see what the new ownership has in store for this place. For now, we will patiently wait for its return :) As for the previous owners, thank you for creating a great place to stop at for drinks, desserts, and food. What a great place this has been for my boyfriend and I to come to. We're not really known to be regulars anywhere but what a joy it was to wake up early and stop by here at Teaish.
