Wonjo Hongneungak is an old Chinese restaurant near Gyeongdong Market and Cheongnyangni Market, a 10-minute walk from Cheongnyangni Station Exit 1, serving yukmi jjajang and tangsuyuk. The signature yukmi ganjjajang comes with a thick sauce of finely chopped onion and meat served separately from the noodles, and orders start at two servings. The small dining room has only four tables, so a wait forms, but food comes out quickly. The jjajang and jjamppong taste lightly seasoned to anyone expecting strong flavors.
