There is a vegetarian buffet restaurant there, the name of which I cannot remember, but it was some of the best food I've ever eaten! It was really expen$ive though. Really, really expensive.
That's The Commonsal. I actually don't like their food at all, and it is really expensive. It's by the weight, and they use glass plates, so you're actually also paying for the plate! Not to mention the fact that they're a chain and arn't reknown for treating their employees well. I would just go to Aux Vives on St Laurent instead. Much, much better food, and it's vegan!
