Bokseonggak Deoksugung Doldam-gil Branch is a Chinese restaurant on Deoksugung-gil in Jung-gu, Seoul, serving jjajangmyeon, jjamppong, and tangsuyuk near the Deoksugung stone wall path. Its napjak gochu jjajang and napjak bokkeum jjajang use noodles that are chewier than standard noodles, while the basic jjajangmyeon comes with a thick, sweet sauce. At lunch, office workers and visitors from the area crowd in and form a line, and food typically arrives about five minutes after ordering. The shop is small, so it fills to capacity and a wait forms at lunch.
