Loud, noisy, packed, and hot. I'm not a huge clubber anyway, but this place is on everybody's list in Quebec, so I went to see what all the fuss was about. I guess, as clubs go, it's pretty cool - there are three floors so you can always try to find someplace a bit less raucous. The music is ear-piercingly loud, and by midnight, there's barely room to breathe, not that you'd want to considering how stifling it can get.
If you're into clubs, this one is supposed to be fantastic, but I can't stand the noise and crowd and heat. Drinks are relatively reasonable. And, this is THE young scene in the city. Worth a look, but, if you're not into clubbing, don't plan a whole night around the Dag.
