Pretty bad place.
Let's start. Bouncers where really rude from the beginning. I was alone (my friends where already inside) and i talked to them in english (my mistake). No way to get in. As soon as i started with my little french they where more friendly and finally let me in. That's the one star, otherwise it would be zero.
Inside it's crapy, stinky (there weren't many people) and filthy.
Totally overpriced. Tapped small beer 5 € (wasn't possible to get one), 10 € for a 33cl bottle of Heineken and 15 € for a really bad, tasteless cocktail. This are prices you'll find in top places in Paris.
As it's in a basement they don't have reception. You don't have to make calls in a club, but because of this sometimes their credit card reader doesn't work. So just cash!!
Finally the music.
I didn't like it, but that's just personal taste and doesn't affect my judgment over this place.
If you want go for it, but there are some really better places in Paris.
