Good for him, I guess. I know two (2) Muslim gays, though neither of them live in NYC.
I'm not going to bother being offended, but it's sad that this guy doesn't recognize that gay Muslims have their choice of every other gay bar in the city if they want to go out, and don't have much trouble meeting other gay Muslims if they want to. How is he going to "cater" to Muslims in particular?
Edit: A floor serving no alcohol--that's considerate. In my experience, the way bars make that work when they have to (liquor license cuts off before closing time) is by charging a hefty cover, which could be tough. Anyway, let's see if this goes anywhere in a week or so...
