Hwajeon Son Kalguksu in Busan serves kalguksu (knife-cut noodles), bibim kalguksu, and other noodle dishes. Kaljajang is lightly seasoned, while bibim kalguksu comes with chewy noodles and broth. The dining area is small, so queues form. Corn noodles and gamjajeon are also available, and the noodles in the kalguksu and bibim noodles have a noticeable noodle smell.
