Stopped by on Saturday, 01/11/25 for the first time. I ordered the matcha latte (warm) which was a bit strong and wished it was a bit more on the sweet side. the matcha authentic taste was definitely there though. Great vibes, clean interiors, and lots of folks studying and/or on their laptops. A nice place to catch up with friends.

I got the Strawberries and cream latte. My friend got the Dalgona latte. These are the 2 popular drinks according to the menu. I thought strawberries and cream was a tad too sweet. I should've ordered it less sweet.

Great ambience, great drinks, nice selection of pastries, plus they have the best music. Come early to claim a space because they fill up quickly. it'll be worth it!

I was around the area and we wanted a coffee to try, I was feeling something strawberry and it was very yummy but I forgot how expensive things are now. Almost 20 bucks for 2 drinks. If you ever want to do some work out and relax at a coffee shop I think this is a nice place to get some work done. You order through a kiosk and we did have to wait a while but I think it was just busy hour.

The coffee was good, I ordered a Cappuccino with honey. They charged ¢75 for honey in person vs no charge ordering online so my drink was $6.75 for 1 cappuccino! On the more pricy side. But other than that the service was nice. Working/Studying: There are many seats and a good number of wall plugs if you are planning on getting some work done . And they got WiFi. There are seating area where I can stand or sit while working, I like that for my legs! The shop gets pritty loud if it's crowded but the vibe is nice. The restrooms are not in the coffee shop but though a door outside and down a hall for that bathroom break. I can see parking being a problem if you come durring a busy time for the other shops in the plaza.

Baristas don't really acknowledge you when you are at the counter to order for several minutes. I should've done an online order because it would've been faster than just standing there. Not sure if it's a social anxiety thing for them- and I'm totally not trying to be a Karen about it. It's just plain awkward to lock eyes and then get ignored for 7 minutes straight? It's a weird vibe in there in general; service isn't the friendliest/maybe management sucks and it's wearing down the staff? Who knows? Lots of students studying so, not a lot of seating during peak hours. It's relatively quiet for a coffee shop. Music is not playing super loud. Some bench seating and a good amount of tables, if you do get here early to beat the crowds. I think in the beginning when they first opened, they were very coffee-centered and all about specialty beans; but nowadays they seem to focus on the sugary drinks. I tried to give them another chance but I think the quality does not really justify the price. But then again, this is Diamond Bar- not LA or OC; not a lot of great coffee shops in the area in general. The matcha isn't very high quality and my matcha latte was not very concentrated (tasted mostly like milk). Their strawberry purée is really tasty though. The drink was $7.66. I don't think it's worth the price. Then again, this is Diamond Bar- not much competition here.

Love this place. Great place to do work and have a great cup of coffee. Part of a plaza and business building. Parking spots outside but not as plentiful as possible. Bathroom in another building.

Love the aesthetic/ambiance of this place! It's a great place to work. It has lots of seating & decent amount of outlets. Wifi works great, even when it gets really busy. There's also a lot of food options & a public restroom next door. The strawberry matcha & the dalgona latte were decent (i'd give both a 7/10). They also have tablets where you can order on your own.

This place wins in all 3 categories, the food/drinks, ambiance, and parking! Food: if you love croffles you must try this place! Starting at $8 they have the best croffles I have had so far in the 626. First of all the price beats the cafes in Koreatown and they are consistent with the quality of the croffle. They also have a wide variety of other desserts but my favorite is the croffle! I am also a big fan of their matcha series, the matcha is smooth and not too sweet. Ambiance: Plenty of seating with tables and countertops. Service is quick here with two self ordering kisoks. Typically see people studying here rather than chatting. It does tend to get crowded during peak afternoon hours FYI Parking: big parking lot with plenty of spaces!

I'm new to Walnuts and I'm glad I found this Cafe. Their baristas are friendly, lattes are various and yummy, plenty of seatings to get work done or study. It's a great place for meet ups and open hours are long (7am-10:30pm). Parking is kind of crowded despite the plenty spaces, lucky they have additional log underground, so you're good. Just take elevator up to the plaza! I've been to their other location at Irvine, which was also a great place to do work and study, so I'm so happy to find this location! PS: Orange Espresso Tonic reminds of a nice cocktail!
