We went to a Cafe on the North(ish) side of Chicago and ate Bingasoo
The ones we got were Fruit Bing soo and Strawberry Bing soo but they also have A green tea and red bean Bing soo.
There's some pretty paintings on the outside of the cafe. It was peaceful and very cutely themed as an outside garden on the inside. (Hence Outdoor Cafe) It was worth the trip and definitely recommend.
