Replying to Montreal

My frat is heading up to Montreal in a couple of weeks for our pinning. We have two nights where we are on our own. I have been to Montreal before but didn't really know where to go. I am 22 so I really don't feel like hanging out with the younger crowd unless I have to. So what are some good places to go out and what places are good deals since I am on a budget. And I am sure someone will want to put in their two cents about the strip clubs as well. thanks!
