I visited Atwater Market as part of a food-centred tour of Montreal. The comparisons between this market and Jean-Talon are apt--this is a smaller market but it has just about everything you could need or want, though I think Jean-Talon is a bit better, especially for visitors. But the range of ready-to-eat food is still very good here (and includes something I've never seen before, food from the island of La Reunion in the Indian Ocean), and the prices in general are very good.
