Wasn't too impressed.
Was told it was a nice location to visit with a market inside. The building itself was a standard building, nothing spectacular. There were hints of old-french styling, but it was pretty modern.
The internal market was kinda laughable. All overpriced clothing stores for tourists. Though I was a tourist to Montreal, not to Canada, and you could find most things in Toronto too.
If you want to go for the walk, check it out. But Meh.
