5Gu-yeok Bangbae Main Branch sits near Bangbae Station Exit 4 and serves sulfur duck clay-roast, haesintang, jjukkumi-bokkeum, and wood-fired pizza. The jjukkumi is stir-fried in a spicy sauce with a charred flavor, and the haesintang contains octopus, abalone, pen shell, and mussels. The restaurant has a large basement hall, and the sulfur duck must be reserved in advance. Staff service tends to be brusque.
