Chances are, if you've walked into a gay bar, it wasn't by coinkydink. But sometimes its hard to tell if a place called The End Zone is a homosexual watering hole or a sports bar. (They don't all have rainbow glass bricks under the bar, you know.)

To keep things straight—er, so to speak—here are nine signs that, without a shadow of a doubt, you are indeed in a gay bar.

It's not like going to the bathroom requires any privacy, right?

And even if there is, it's full of guys.

Of course, you might just be in the audience at Cabaret. It's hard to tell.
