Kongmyeondang Sangam Main Branch is a Korean noodle restaurant in Sangam-dong, Seoul, serving kongguksu and gomtang. Soybeans grown in Korea are ground every dawn, and the noodles are made in-house, forming the basis of the signature dishes. Tofu is served before the meal, and a full spread with kimchi jeon and side dishes is also available. The kongguksu noodles are thick and chewy, which may disappoint those who prefer thin, soft noodles.
