The patbingsu was nice and refreshing. We got the large red bean (~$8) - it's big enough to share and there's another layer of red bean once you dig to the middle (except it's kind of frozen and hard).
We ordered the rice cakes which was alright. And we got some ginger tea. They didn't have red bean pancake that day. It also took quite a while to get the food but the owner of the place was very nice.
