Rijin is a Chinese restaurant in Seoul that serves jjajangmyeon, jjamppong, and tangsuyuk, located in front of Dapsimni Market. The owner-chef, formerly a chef at Hotel Shilla, prepares chewy noodles, gajibokkeum, and baekjjamppong. The tangsuyuk arrives with the sauce already poured over it, so diners who want it on the side must say so in advance, and rice dishes come with a bowl of egg soup. Service is rough: when the restaurant is busy, hall staff are slow to respond and basic greetings are skipped.
