Hamheung Gombo Naengmyeon is a naengmyeon restaurant that opened in 1968, located on the fourth floor of Sewoon Square near Jongmyo in Seoul. It serves hoe naengmyeon and bibim naengmyeon, with chewy noodles and spicy seasoning, along with mandu. To reach it, take the elevator from the side entrance by the Jongmyo parking lot, and pay in advance when ordering. There is no sign, making the fourth floor hard to find, and the walk in from Jongno 5-ga or Jongno 3-ga is inconvenient.
