A foodie's heaven!  I only spent about an hour here since I didn't have that much time left in Montreal, but the next time I come back I would love to spend a whole day here and peruse every store.  This place is twice the size of Marche Atwater and has a lot more ethnic food stores.  What's really amazing is that the people who work here are so friendly and proud of their organic/fresh/high-quality products.  Words can't explain how exciting it is to visit the Jean Talon market, so go look at the pictures and go there yourself!
