Finally a Korean dessert place that's good enough so I don't have to trek out to Koreantown! It was packed for a Sunday night and considering this place opened under a month ago. Its a small place, maybe about 15 tables or so. It's set up more as a self-serve style, so you take a menu and sit wherever you'd like. Once you decide on your order, you go up and order and they'll give you a buzzer which would notify you to pick up the food when it's ready.
I ordered a large green matcha bingsu ($11) which was good enough to share between 2 people. There are cup, small, and large sizes available. Think of red solo cups (a little taller but less circular) for their cup size, it's enough for one person if they just had dinner. Small and large can be shared by two people. Considering the place was packed, the wait wasn't too long- about 5-10 minutes for the ice cream which wasn't too bad. They do have other hot and cold drinks available and some other desserts such as brick toast. Water is available - off to the side. Debit and/or cash only.
Would come back again to try their different flavours!
