I can't emphasize how much I appreciate that there's a place like Café Verdure on campus. Montreal typically doesn't have much in terms of vegan/gluten-free, and Café Verdure makes up for it.
I've had pretty much the full gamut of dessert/snacks, and I've yet to be disappointed. Not to mention that everything is organic and inexpensive.
I highly recommend that you try this place before it gets too well-known.
