Cafe Chamse Bangatgan is a small cafe in the back streets of a residential area in Sadang, Seoul, selling mango cake and gluten-free rice desserts. The cakes, brownies, madeleines, cookies, and financiers are made with rice, and coffee and yogurt smoothies are also served. Decaf cold brew is available separately, and Americano can be ordered for takeout. The space is small, so it gets loud when it is crowded.
