(I don't know how, Illven, but without prompting, you picked the gay bar.)
Driving to the club, Liz is unimpressed by the plain brick front of the building, with a single door and staircase leading up into the club proper.
The loud techno beats that assail her upon entering, however, signal an immediate change of atmosphere. Some people are dressed normally, in after-work attire. Others out for a night on the town or for dancing. Then you start seeing the people wearing leather straps, with facial piercings and interesting hairstyles.
It doesn't strike you immediately, but it seems the boys are dancing with boys, and the girls with girls for the most part.
The bartender, a cute, ripped guy with a spiked fauxhawk and no shirt waves at you as you enter. Strobing lights of varying colours play through artificial fog on the dance floor.
