Haesong Banjeom is an old Chinese restaurant in Busan that serves jjajangmyeon and tangsuyuk. Its signature dish, Sacheon Jjajang, features thick, clingy noodles with a bit of seafood and tastes like bokkeum jjamppong. The dining room and tables are kept clean despite the restaurant's age. Sacheon Jjajang is spicy enough to overwhelm those who cannot handle heat.
