Kkachi Sanga is a retro-concept cafe selling coffee and drinks in the basement of Jeonnong-ro in Jeju. It serves drinks such as ssanghwa shufener and parfait in an interior styled after old Korean dabang. Old songs from the 1970s and 1980s play in a space furnished with vintage toys and reception-room items, and the dabang atmosphere carries from the staircase. The cafe also sells books, combining a cafe with an edited store.
