Dongchuni Mandu is an old dumpling shop in an alley near Danggam Market in Danggam-dong, Busan, selling hand-made mandu, hand-cut kalguksu, and hand-torn sujebi. The kalguksu noodles are cut by hand with a knife, and the shop also sells steamed buns. On weekends a wait forms. The interior is old, small, and cramped.
