Kim Gwangseok Sinchon Kalguksu Idae Direct Branch is a restaurant in Daehyeon-dong, Seodaemun-gu, Seoul, closer to Ewha Womans University than to Sinchon, serving mushroom spicy beef shabu-shabu and kalguksu. Diners eat the beef, mushrooms, and water dropwort first, then finish with chewy kalguksu and fried rice made with perilla oil. Seats fill up even on weekday evenings, and mushrooms and kalguksu can be added for free. The side dishes are just one kind of baekkimchi, so the spread is simple.
