LOVE IT!!! It’s a 15 min drive from home but totally worth it!! Best coffee around Walnut and diamond bar area.
The latte is full of flavour and the topping is delicious! Lots of cute dogs in the shop so it’s totally pet friendly. Try all their interesting lattes, you will be coming back for more!

This coffee shop has a unique interior—simple yet modern—with flexible seating that lets you arrange tables and chairs for comfort and space optimization. The WiFi is reliable, and there are plenty of outlets, making it a great spot for studying. The cafe latte I ordered was reasonably good.

Interesting location with a wide variety of drinks and pastries. No stand outs but I really liked how they did their seating so that they are able to accommodate despite the small location. I was there to catch up with a friend.

The coffee is good. I love supporting local coffee shops. But service is slooooooowww… it’s always busy here. You’ll be waiting about 20 minutes for 1 drink.

Great coffee but you can be waiting over 20mins for your drink. That's also if they don't forget about your drink. If they do, it came take more than 30 mins.
I have been a few times and I seem to see the same issues every time.

Great place for matcha, atmosphere, and service. Good range of dairy alternatives: soy, almond, oat, coconut. 10/10 would come again if I was a local.

Not an expert on coffee, but the lattes were fine for me. However, the service and atmosphere is perfect. The minimal-style interior design and quiet environment is perfect, especially no music & no loud conversation. Good place for study and work without headphones.

Not for coffee people. If the barista said Dalgona coffee is their best seller, you better think twice ordering. Ordered Kyoto cold brew (tastes like old stock coffee), & Passionfruit Espresso Tonic. I asked the barista why my drink doesn’t have that tonic water taste. Barista said they use sparkling water for tonic water (It’s like that’s what they’ve been doing). No apologies received from the barista. So, I just shook my head and left. There are better coffee shops around the area (at least two across the street. Better go there. Very disappointed.
