Haetteuneun Janchi Guksu is a noodle shop in Gwanak-gu, Seoul, serving janchi guksu and bibim guksu. It makes its own saengmyeon and ages it, rather than using standard somyeon, so the noodles are chewy and do not soften quickly. Both janchi guksu and bibim guksu can be ordered as large portions. The broth is milder in character than the noodles.
