24 Si Yongsan Wonjo Gamjatang is a gamjatang (pork bone and potato stew) restaurant across from the west plaza of Seoul Station that stays open 24 hours. Its mukgeunji gamjatang contains pork bones, aged kimchi, and potatoes, and the broth tastes like something between kimchi stew and gamjatang. The stew is boiled and then served out to eat, and a dipping sauce can be requested separately. The amount of meat is on the small side.
