Walk past the Namyeong Station in Yongsan into a small alleyway and you’ll see a hanok (traditional Korean house)—or just look for a house that stands out from the rest. It is at this 100-year-old house that Gangwonjung set up shop to serve its signature samgye-tang all year-round. Founded in 1978, the restaurant is now owned by Ham Ho-sik, the son of the founder. The quality of the samgye-tang is definitely one of the main reasons the restaurant has stayed open for 39 years. The commitment of the restaurant can be felt in a single bowl: using domestic poultry that is more fully grown than other restaurants, the broth is boiled for up to two hours to create a rich flavor. Be sure you get your fill for lunch or dinner (there is a break between three and five o’clock in the afternoon).
