Somanan Son Kalguksu is a noodle shop in Busan that serves kalguksu and gimbap. Its cold kong kalguksu uses kalguksu noodles rather than the usual kongguksu noodles, and it is eaten with gimbap on the side. An elderly couple runs the shop, and the kimchi is taken from a shared container as needed. The noodles are boiled slightly firm.
