Haecoseom is a Korean restaurant on the ninth floor of Hyundai City Outlet Dongdaemun in Seoul. It serves set meals with seaweed and seafood, including a seaweed bibimbap and bossam set that comes with maeuntang, a spicy fish stew. The set includes many side dishes, and the main dishes and seafood are generally good. Serving staff are few, so responses are slow even when the call bell is pressed.
