Sangeun Bukeoguk is an old restaurant in Yeouido that serves bukeoguk, aukguk, and a lunchtime dongtaetang. The bukeoguk is a hangover-relief dish, and the dongtaetang comes with thick chunks of fish. It opens at 6 a.m., the dongtaetang is available only at lunch, and it closes around 2 or 3 p.m. The staff's service is rough, so take care.
