Haemul Wangchang Kalguksu is a kalguksu restaurant in Busan that serves seafood kalguksu, mandu, and haemul pajeon. The broth is boiled like a clear seafood soup, and the seafood is taken out to eat first before the kalguksu noodles are added. At a machine in front of the store, entering a phone number sends a ticket number via KakaoTalk, and pre-orders can be placed on a menu sheet. Cooking takes time, so on weekends the wait outside in the sun is long.
