NewTown is the hottest club up there right now. It's hard to get into if you don't have passes so use the concierge at your hotel. I was just in Montreal 3 weeks ago and our concierge managed to hook us up with 6 vip passes; he also managed to get us 4 good tickets to the Montreal-Toronto hockey game 1 hour before the start
. For your afterhours needs you could check out Sona(opens @1:30a.m. no drinks served) but I believe the new hot afterhours club is Aria. If you like ribs I would recommend eating at Barby Barn, the ribs are awesome and huge so only order the whole hog(9 ribs) if you are extremely hungry.
