Haeon Guksu is a noodle shop in Okpo, Geoje, serving janchi guksu and bibim guksu. The noodles are yellow and chewy, served in an anchovy broth with bean sprouts and two garnishes. Even a small order comes out at roughly the size of a regular large portion, and there is a line during lunch hours. There is no parking lot, so cars must be parked in nearby alleys.
