Hyeonchina is a Chinese restaurant inside Bangi Market in Seoul that serves jjajangmyeon, jjamppong, bokkeumbap, and tangsuyuk. Its signature dish is sukju tangsuyuk, served with a soy-based sauce containing cheongyang chili peppers and crisp bean sprouts. The jjamppong contains mussels and one large shrimp, and the noodles are thin. The sauce is not the thick, starch-thickened type, so the tangsuyuk stays crisp down to the last piece.
