Woongkal Seongsu (웅칼성수)

Namdarun Dakhanmari serves Korea's iconic whole chicken soup (닭한마리) — an entire chicken simmered in a light, clear broth with potatoes, rice cakes, and noodles. This Seongsu branch maintains the traditional recipe that has made dakhanmari famous in Dongdaemun. Recommended because dakhanmari is one of Korea's most universally loved dishes — light, non-spicy broth with tender chicken that even the pickiest eaters enjoy.

Kyejalam is a perfect-5-star charcoal chicken restaurant in Seongsu. The chicken is grilled over charcoal to achieve incredibly juicy meat with a smoky, crispy skin. The restaurant has a kiosk ordering system with multiple languages, making it exceptionally easy for foreigners. Fun fact: the restaurant features SEVENTEEN (K-pop group) posters. Recommended for its flawless charcoal-grilled chicken that delivers smoky perfection — combined with a multilingual ordering kiosk, it's one of the most accessible Korean restaurants for tourists.

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.

Dwaeji Gomtang Hau serves pristine clear pork bone broth slowly simmered at low temperature and high pressure, resulting in a silky soup unlike heavier milky versions found elsewhere. Also features Pyongyang-style cold noodles and pork cheek seaweed soup. Ideal for travelers wanting authentic Korean comfort food without heavy spice.
