Ido Yongsan is a small bar-style restaurant serving Korean food on Yongridan-gil, close to Samgakji Station. It serves miso ramen and Korean potato pancakes cooked in a pan, and it is the restaurant of chef Lee Seungjun, who appeared on Culinary Class Wars. When food comes out, lighting casts a single beam on the plate, and there are cases of visiting without a reservation. One chef and staff member work there, so service is slower than at other places.
