KL has a pretty good gay scene. My favs are Frangipani and Bliss. Both are in the Bukit Bintang area near your hotel, and both are busy during the weekend. Beautiful boys too :-) They both have bar areas and dance floors. The music can get pretty loud but you can escape from it easily. Not sure if KL has a gay venue that's just a bar per se, like Backstage in SIN or Balcony in BKK.
