Halmeoni Naengmyeon 할머니냉면

For 50 years this shop near Gyeongdong Market has served only spicy naengmyeon, and the single-dish menu keeps turnover fast even with a line. The chili sauce on the thin, springy noodles is hot enough to be compared to fire noodles, and pouring in the cold broth served alongside turns it into a soup bowl without taking the burn away.
