Woo Lae Oak is one of the best Pyongyang naengmyeon restaurants in Seoul, and its reputation and traditions have been upheld since opening in 1946. The broth is what sets this place apart from the competition. It is made by boiling hanwoo foreshank for hours and seasoned with nothing more than salt and soy sauce to create the clean savory flavor that can only be tasted here. The bulgogi, which is another popular dish, pairs well with the cold noodles. It has been maintaining consistent flavors through its many years of service, and exclusively using local ingredients. This historical establishment is packed with diners around the clock.
