Koike is a cafe in Yeonnam, Seoul, that sells cakes, baked goods, tea, and coffee. The cakes have cute decorations and a low level of sweetness, and the shop also serves madeleines and teas such as Earl Grey, rooibos balance, and fruity chamomile. It began on the second floor and later expanded to the first floor, and drinks can be ordered with a choice of milk. During busy weekend hours the noise level rises and conversation is hard to hear.
