I went with Korean friends and a promotor so I got free entry and unlimited free alcohol. Usually you have to pay and they can be weird about letting foreigners in (I would be one of the only 1-3 foreigners there). I went to the HipHop room usually when rappers were performing so the club was very crowded. I would only go when there are rappers/singers performing as that is when the vibe is the best. If there are no performers, people here don't dance much, just stand around and try to look as cool as possible. There are older men who reserve tables and then spend the whole night begging girls to join them. Smoking isn’t allowed.
