Byeolmi Sundaeguk Main Branch is a sundae-guk restaurant on the first floor of the Gyodong Workers' Welfare Center in Sokcho. The broth is made without off-flavors and contains house-made sundae and various cuts of meat, giving the soup a clean taste. Because of health reasons, the restaurant's opening hours are short, and it closes when ingredients run out. It is located inside the welfare center, making it hard to find from the outside.
