Ilmi Son Kalguksu is a long-established restaurant in Godeok-dong, Seoul, serving kalguksu (knife-cut noodles), sujebi (hand-torn dough soup), kaljebi, and kongguksu. The restaurant cooks its hand-kneaded noodles and sujebi to order in anchovy broth. Noodles are made when ordered, and kongguksu is available as a seasonal dish. The owner runs the restaurant alone, so service is not fast.
