Jean-Talon Market is not only the biggest outdoor market in Montreal, it's one of the biggest in all of North America. The huge row of vendors (covered during the chilly season) seems to go on forever, and around the periphery, there are a bunch of great shops for Québec cheeses, maple products, gelato, hanging meats, fresh-caught fish, and ciders. You can have a whole meal there or just graze on apple slices and bumble about. Here are some favorite stops.
Every gelato and sorbet flavor here is killer, especially the maple brûlée (with all the crackle bits inside), strawberry with black pepper, Masala chai, pear cider, and grapefruit. They are super patient with sample monopolizers too. Look for new flavors on the blackboard.
