best dancing clubs in Busan

Hi all, My friend and I are visiting Busan this weekend and are looking for a club to go dancing in. I researched on the web and decided we will go to Haeundae or Seomyeon. I am not sure which club to go to, though. We want to go somewhere that is just about dancing, not just a pub or bar that happens to have a dance floor. We were thinking...super crowded, everyone dancing, loud music. Any suggestions? Thanks so much.
