Any advice for a gay traveler going to Paris?

Going to Paris in a few weeks. Anyone have any information to pass along? Places you've gone and shouldn't be missed? Things that weren't as awesome as you thought they'd be?

Mexico Traveler asked why specify that I'm gay. (Nobody get bent out of shape - it wasn't asked rudely.) It's really a case of "if you were you'd understand," but let me give it a shot.

Yes, I'm interested in knowing about the clubs and bars. While that is not the intent of my trip, I am interested in going out at least a couple nights and would like to hear from others like me where they've enjoyed going.

Also, there might be places of particular interest to a gay traveler that a non-gay traveler wouldn't feel was noteworthy. It never hurts to ask.

And finally, unfortunately - and I know this isn't an issue in Paris - there are some parts of some cities that a gay person should avoid at all costs.

It's kinda funny that you would ask me this. The reason that I specified "gay" is that most of my friends are straight, so most of the travel advice I got was the general tourist stuff. I posted the question because I wanted the specific gay experience.

Thanks for asking!
