Looking for a Montreal experience? Look elsewhere- and I don't mean that in a bad way, I mean that in a matter-of-fact way.
Rue Sainte Catherine resembles a typical street in a typical downtown area in a typical city- with chain stores that you can find in the US and other places in Canada. Great place to go shopping as a local; as a tourist, visit your own version of Rue Sainte Catherine back home and spend that time at places that are unique to Montreal.
