Wenson Udon Jjajang Tangsuyuk is a Chinese restaurant in Imun-dong, an 8-minute walk from Exit 1 of Hoegi Station, selling udon, jjajangmyeon and tangsuyuk. The thin, springy noodles are coated in a sweet old-style jjajang sauce, and spicy udon is also a signature dish. The small shop has wood interiors and a clean dining area, and a set that pairs tangsuyuk with a meal lets a solo diner eat both together. The tangsuyuk is sliced thin enough that the meat is barely noticeable.
