Bak Manbae Arirang Bossam Seongsu Branch is a bossam restaurant in Seongsu that serves gabrisal suyuk and kalguksu. The suyuk is moist and tender and comes with kimchi, and the kalguksu is served in a refreshing crab broth. Around 8 p.m., the inner seats are not visible from outside, and two tables of customers were drinking. Even the smallest size is a large portion, so it is a lot for one or two people to eat lightly.
