Kalguksu Kongguksu Jip is a noodle shop in Cheonho-dong, Gangdong-gu, Seoul, at the far corner of a market alley. It serves bajirak kalguksu made with plenty of clams, giving the broth a clean taste, and the kimchi is good as well. Orders can be placed by the single serving, and in summer naengmyeon and kongguksu are also served. The space does not have a young vibe.
