Kuidoraku is a Japanese ramen restaurant in Anam-dong 5-ga, Seongbuk-gu, Seoul, near the Anam intersection and Korea University. It serves tonkotsu ramen, miso ramen, and shoyu ramen, with unlimited refills of rice and carbonated drinks such as cola and cider. University students line up at lunch, and the seating is narrow enough that meals are sometimes served in an annex. Hall management is poor, which raises hygiene concerns.
