Let's not forget:

Sky, Stock and Campus in Montreal
Backstreet and The Armory in Atlanta
Badlands in San Francisco
Little Jim's in Chicago
The Cock in New York, since La Bamba's Olympia Lounge and Stella's are both closed now. Where Stella's was is now some place called Otis? There's also a nice little bistro/bar on 10th Avenue named, appropriately, Xth, IIRC. And the old standbys, The Hangar and Stonewall.
Did I mention Rupert's in London?
The Berlin Connection and Anderes Ufer?
The Hotline Club in Milan
The Barn in Toronto
Tasca Don Sol in Caracas

and that's just the PG-rated list...
