Milyang Son Mandu serves mandu-guk and kal-mandu-guk with fist-sized handmade dumplings near Eonju-ro in Seoul. The kal-mandu-guk comes with one kimchi mandu and one meat mandu plus kalguksu noodles, and the broth is not spicy. On weekday lunch hours the place fills with office workers from nearby, though tables turn over quickly. At lunch a crowd gathers and you have to wait.
