Songpa Gamjaguk is an old restaurant in Seokchon-dong that serves gamjatang, a pork bone and potato stew. The stew comes with meaty bones, large perilla leaves, and perilla seed powder, and the meal ends with fried rice made in the remaining broth. On weekday evenings at 6 p.m., a wait of about 20 minutes forms. The room has about six tables, so the line continues after the seats are full.
