Seobu Gamjaguk is an old restaurant in Eungam-dong that serves clear-broth gamjaguk and ugeoji gamjaguk. Pork backbone and whole potatoes are boiled for a long time, and the meal is finished with geotjeori kimchi and bokkeumbap. It is open every day from 11 a.m. to 11 p.m. with no break, about 600 meters from Exit 3 of Yeokchon Station on Line 6. There is no single-serving haejangguk-style menu, so a solo diner has to order the small size of gamjaguk.
