Kkotbing is a large cafe on the second floor of the Dongseoul Terminal in Seoul that sells coffee, bingsu and cake. It serves bingsu, cake and coffee together, and many customers stop in briefly before their bus time. It gives people somewhere to wait when the terminal's first floor has no seating or when there is time left before a bus, and the store is fairly spacious. On weekends there are many customers, so service tends not to run smoothly.
