Imun Seolnongtang has been serving its hearty seolleongtang for nearly a hundred years since it first opened in 1907. Even its name has a long history: the word imun comes from Imun-gol, the now-obsolete name of the restaurant’s location, and seolnongtang, an old variation of the word seolleongtang. During the Japanese colonial rule, the restaurant’s regular customers included Gijeong Son, the marathon gold-medalist at the 1936 Berlin Olympics. To make the rich seolleongtang broth, beef meat and bones are simmered for more than 15 hours. Try putting rice and minced green onion in your seolleongtang for a warm and tasty experience. Kkakttugi (diced radish kimchi), provided as a side dish, is also delicious. TIP: Kkakttugi and kimchi are available through self-service. Pay for your meal in advance.
