Hi, I recently (a week ago) went to Paris and tried to find most of these bars. Don't bother! There's only three of them left, le so what, 3W and the former unity bar, now called.. les mutilieres (?) or something similar to it.
If you can only go to one, go to the former unity bar (176-178 rue St-Martin, 75003 Paris). It's a nice and cozy place where you can meet amazing people. Everyone is super nice and the place is extremely transfriendly! Once I walked in there in I felt like I never wanted to leave.
3W was very crowded and the music sounded a bit off. You propably wont be able to sit or dance in there on a saturday night but if you bring along a few friends you'll still have a blast!
Le so what is open until 5 am, so if you're planning to go there you should savor it for later in the morning unless you're planning to spend the night alone in a empty club.
Have fun everybody and stay safe!
And timeout should really update this list, I would have saved a lot of time and patience.....
