Biryong Son Jjajang is a Chinese restaurant in Busan that serves jjajangmyeon and jjamppong. The noodles are hand-pulled, the jjajang is not very sweet, and the jjamppong is not spicy and has a clean broth. The noodles are thick and chewy, but they can retain a flour taste or break apart easily. The ganjjajang is served with the jjajang sauce on the side rather than mixed with the fried sauce.
