Songgane Gamjatang Main Branch is an old restaurant in a back alley of Yeonnam, near Hongdae Station, serving gamjatang, bone hangover soup, suyuk, and jjukkumi. The gamjatang is eaten with ramyeon noodles added, and the set comes with stir-fried jjukkumi, dubu kimchi, and suyuk. It is open 24 hours, and a wait forms if you do not arrive early; the second floor opens for large reservations or when the first floor is full, and side dishes are self-refilled. Eating alone is difficult because the minimum order is two servings.
