Somonnan Son Kalguksu is an old neighborhood snack shop across from a bus stop on the Geumjeongsan hiking trail in Busan, serving kalguksu and gimbap. The menu includes myeolchi-yuksu kalguksu, son kalguksu, bibim kalguksu, naengkong kalguksu, and kal mandu. The kalguksu noodles are chewy and the myeolchi-yuksu broth is clean-tasting. The gimbap is the basic style.
