Myeongdong Hongdukkae Sonkalguksu 명동홍두깨손칼국수

Inside Macheon Market, this small noodle shop kneads and rests its dough every day, then cuts it by hand and boils it in a mild broth. Son kalguksu (hand-cut noodle soup) starts clean; partway through, stir in the spicy sauce on the table to turn it hot and bold. In summer, cold kongguksu made from seoritae black soybeans joins the menu. At lunch the line stretches outside, there are no reservations, and the market has no dedicated parking.
