The Marché Bonsecours de Montréal is an incredible building with a ton of small shops as well as unique vendors. The majority of the items in this Marché are fairly expensive but if you are looking for some interesting art, for your home, designer clothing, or a place to spend some time at a cafe, then this is the place to visit.
The overall feel here is really great but again be prepared to shell out a lot of money for some merchandise. If your wallet isn't that thick, then you can do what we did and just wander enjoying the window shopping.
