Gupo Chueotang is an old rice restaurant in Deokcheon, Busan, serving chueotang and dolsotbap. The soup is made by grinding whole mudfish and boiling them into a clear, clean Gyeongsang-style broth, and it comes with soybean and black rice dolsotbap, braised mackerel, ssamchae, and several side dishes. After the rice is removed, seungnyung can be poured into the dolsot to finish the meal, and delivery orders come without side dishes. At lunchtime there may be a line or no seats available.
