Somunnan Gamjatang (소문난감자탕)

One of Seongsu's most iconic local restaurants, Somunnan serves rich pork backbone stew (gamjatang) that has earned it nearly 6,000 Google reviews. The stew is simmered with tender pork spine, potatoes, and perilla seeds in a mildly spicy broth. The generous portions and affordable prices draw long queues of locals daily. Recommended for its authentic, no-frills Korean soul food experience that foreigners consistently praise as surprisingly approachable — not too spicy, deeply flavorful, and incredibly filling.
