Daegwallyeong Gamja Ongsimi is a restaurant near Changdong Elementary School in Dobong-gu, Seoul, serving Gangwon-style potato ongsimi and buckwheat kalguksu. The chewy potato dumplings and buckwheat noodles come with barley rice and yeolmu kimchi before the meal. Cooking takes a while, so diners mix the spicy mu saengchae with barley rice while they wait. At weekday lunch the restaurant fills with customers, creating a wait, and parking is not easy.
