Kamatake Jemyeonso is a Japanese udon shop in Nampo-dong's Biff Gwangjang, next to the 18 Beon Wandangjip, serving bukkake udon with joktamyeon noodles. It sells chikutten bukkake udon, ebiten, and tantanmen, and the noodles have a chewy, springy texture. The shop is in a basement, where customers order at the counter and carry their own food, and the entrance and stairs are narrow. One person handles the front of house, so tables are cleared slowly.
