A place full of posers, who know very few about music, they are just there "to be seen", like almost every rock bar in Paris.
Avoid!

Nice bar, in the center near to chatelet. It has some preety girls even if the music was somewhat commercial metal-oriented.

I'm from the west of Germany and I'm pretty much spoiled when it comes to bars and clubs. I already went to the blackdog a couple of times and it was always awesome. The music is mostly great and they play also death and trash! It's just that they play sometimes a hole album or weird (and I mean weird, cause I normally like that genre) gothic music.
Prices are like everywhere in Paris and I already heard a lot of times, that you should try the restaurant!!
Enjoy!

went on a weekday by myself- so it was kinda empty (apparently on weekends it's much fuller.. not surprisingly) still the turnover of "metal" people wasn't too bad. the music is good too. bartender was kind of a dick so don't expect to chat him up (course beer is an international language). still, a nice place.

It's also like a 5 meter walk to "le klub" so if youre there on a weekend you'll likely enjoy having the two places to visit.

Great place - Beer a bit steep but Music excellent. I was tucking into a fat juicy steak with decent wine and listening to Br00tal DM after 15 mins of walking through the door. Recommend. Punters are friendly too.

As seems to be par-for-the-course with all rock bars, the pints here were dodgey. However, the lively atmosphere more than made up for this & the tunes ranged from industrial to glam to metalcore. The restaurant is a real gem so be sure to bring your appetite!

If you go downstairs I advise to drink only bottled beer. I don't know what's wrong with their tubesystem but the only beer they pour downstairs is stinky, has a bad taste and sometimes two pints are enough to have an horrible headache... Upstairs it's ok, though. But beware I warned you

Front room is a metal bar cranking metal on iTunes. Mostly good stuff, maybe not enough early 80s classics for my tastes, but decent. Beer was cheap, mixed drinks were not. It can get crowded unless they open the downstairs section of the bar. In the second room of the ground floor is a restaraunt specializing in South American style steaks, which kick ass! I'm pretty sure they had some vegetarian options as well, because I had a killer salad! Its pretty cool eating in a restaraunt where most of the other diners are metalheads!
