Montreal

We're starting to think about our trip to Montreal at the end of the summer. I'll be there for a week (but probably not doing much sight-seeing), and ehs will come up for a long weekend at the end. We're looking for suggestions on any one's favorite things to do in Montreal. So far we're planning to make sure and see the Biodome and the Botanic Gardens, a couple of museums and galleries, the Notre Dame cathedral, the Mont Royal Park, the Old Town, and the boutiquey area of St. Laurent. Please excuse the anglicized versions of these place names. Any other sights we should be sure to hit? Any favorite restaurants?
