Club K Seoul is a large spa one minute from Seolleung Station, combining a sauna and jjimjilbang with a fitness center and a jazz bar. At the jazz bar, guests have ham and wine or a vodka set alongside a Ryu Bok-seong jazz performance. Performances start at 8:30 p.m., and the venue also has a book cafe, a small library, and a health food cafe. In the sauna, no towels are provided inside the bathing area, and the temperature difference between the hot, warm, and cold pools is pronounced.
