This place is huge, Mansion is definitely an appropriate name for this place, 4 floors of fun and partying.
All four floors have different designs, DJs and atmospheres. I will say the best of these fours is the top floor. The top floor is basically a patio with a what I believe is a retractable roof. You can go up there dance, get drinks and be under the stars which is awesome on a nice night.
Another cool thing about this club is they have a TV that has a countdown to when last call so you're sure to know when to get in that last drink.
Drinks were decently priced, about what you would expect from a club in a major city.
Another great concept that I think needs to be adopted more places is this place has coed bathrooms. Mansion realizes this is 2012 and women and men can go to the same bathroom and not have to worry about people being pervy. I applaud Mansion for being so modern.
This is a cool club in Toronto to go out, have a good time and just get into the groove. Worth a visit.
