Yes Toque is awesome!
But there's more to Montreal than this.. For lunch one day go to Schwarz's deli. Holy moly I was blown away by their reuben sandwich.. as a former New Yorker I can say that it was very much up to par with Stage or Carnegie in NYC. Awesome if not better!
Montreal can also have some EXCELLENT hot dogs..
In Old Montreal there's some great little Boulangeries with good coffee and excellent croissants.
You can probably skip the poutin (chesse curds, fries, and gravy). Unless you're going out on St. Denis and need some late night munchies. But then again, I think there's a 24hr McDonalds on St. Denis. Ahhh, St. Denis.
