Doyajjamppong Dongnae Direct Branch is a Chinese restaurant in Busan that serves jjamppong, jjajangmyeon, and tangsuyuk. The jjamppong comes with a spicy broth and chewy noodles, and tangsuyuk and one- or two-person sets are also available. When orders pile up, the wait gets long, and the evening jjamppong is sometimes lukewarm. The vegetables are soft, so there is little to chew.
