Yangjeongwon is a small Chinese restaurant in the alley of Mallidonggogae in Seoul, serving ganjjajang and tangsuyuk. The ganjjajang is thick and the noodles are chewy, and the tangsuyuk comes in an old-fashioned style. It is run by the parents of Jungwon, a member of ENHYPEN, and delivery is limited to nearby areas. The small dining area has only three tables.
