Gangseonghwan China is a Chinese restaurant in Seoul that serves jjajangmyeon, jjamppong, and tangsuyuk. It also serves dishes such as nurungji tang, yangjangpi, gganso saeu, chapssal tangsuyuk, and ggapunggi. The dining room is larger than it appears and has many seats, and food comes out quickly even after a wait. The flavors are ordinary, not worth a special trip.
