Ojang-dong Hamheung Naengmyeon (오장동 함흥냉면)

Ojang-dong Hamheung Naengmyeon originated when grandma Han Hyesun, who migrated from Hamgyeongnam-do to Seoul during the Korean War, began selling Hamheung-style "nongma guksu (starch noodles)," eventually naming it Hamheung naengmyeon (Hamheung cold buckwheat noodles). Its signature dish, bibim naengmyeon (spicy buckwheat noodles), features chewy noodles infused with a tangy-sweet seasoning, showcasing the expertise behind its preparation. Alongside the flavorful broth served as a base, the menu also includes variations like hoe naengmyeon (cold buckwheat noodles with raw fish), mul laengmyeon (cold buckwheat noodles), suyuk (boiled pork slices) and mandu.
