Mandorong Haejangguk is a hangover soup restaurant on Taepyeong-ro in Seogwipo. Its signature dish, gengiguk, is a seaweed soup made with ground small crabs and served with two abalone. Arriving early in the morning means being seated right away, but a queue forms after 8 a.m. The gengiguk and the side dishes are seasoned on the salty side.
