This place has the best teas in town. I'm a big tea guy and no other place I can think of has better quality and better tasting tea. Not only that, the art that goes into the drinks makes this place one of it's kind.

Cute and friendly. Chill atmosphere and family friendly. Got two drinks and both were a hit! My kiddo was amazed by the mini boba with the Hokkaido milk tea and I am in love with the dreamy matcha of the Ronin! Definitely will be back

I go here often because it’s so delicious!! The staff were all very friendly and I tried almost everything on the menu and it was all good. If you like strawberries, try strawberry yogurt. It's so refreshing that you'll keep drinking it.
The atmosphere of the store is cozy and nice, so I think I'll come here more often.
