Tongnamujip Jjolmyeon Tteokbokki Jeonmunjeom is an old snack shop on the edge of Gusan-dong in Eunpyeong-gu, Seoul, selling only jjolmyeon and tteokbokki. The tteokbokki tastes homemade and is less spicy, while the jjolmyeon has a distinctive sour sauce. It opened in 1983, and once you sit down the staff prepare your order without being asked, with the food arriving quickly. The jjolmyeon portion is small, so it is not enough for a meal.
