Sanshoku Ramen Gangnam Main Branch is a Japanese ramen shop near Gangnam Station serving tori paitan and tonkotsu. The white tori paitan, made by simmering chicken for a long time, comes with a soft, rich broth topped with a soft-boiled egg and chicken, and the salt level can be adjusted. A self-service bar offers unlimited refills of rice, and the space has wide seating that makes it easy to eat alone. The location of the water cups is not easy to spot, and the dish return spot is confusing at first.
