I'm going up to Montreal Thursday-Monday for a conference. I don't know how much time I'll honestly get to explore the town, but if I do have some time... what are some must-sees? I don't care much if I miss tourist sites, but I like to know about good restaurants, cool shops, nice views, photo opportunities...

Money-saving is a must as I'm not getting much funding from my dept. for this trip and all my money is focused toward the wedding now.
