Sinchon Jeuksok Saeng Udon is a udon restaurant in Seoul that serves thick fresh udon and tonkatsu. The noodles are made in-house and served in a broth of anchovy stock and spicy chili, with mugwort added. Even at minus 10 degrees, around ten people wait outside, and the shop only serves meals, so tables turn quickly. The space is small with narrow gaps between tables, making it hard to sit comfortably.
