Jjajang & Tangsuyuk is a neighborhood Chinese restaurant in the alley market of Jayang-dong, serving jjajangmyeon, jjamppong, and tangsuyuk. Its jjamppong broth is mild and light, and the noodles have a good texture. The restaurant is run by a married couple, closes on Mondays, and handles almost everything from ordering to clearing tables on a self-service basis. Because it is inside the market, food smells and hygiene can be drawbacks.
