With all of the other veggie and vegan options in Montreal I just have a tough time getting excited about what's on offer at Le Commensal. This is essentially a pay by weight buffet/cafeteria and as such suffers from the freshness issue that it endemic to the delivery system.
Le Commensal gets a lot of extra love (in the stars department) because of choice. Most veg-heads are frequently subjected to a rather frightening level of same-ness in available dining options. The reason that love doesn't extend past two stars is that although there is variety, quite a bit of it tastes the same and I have yet to have experienced anything worthy of remembering well enough to include in - oh - let's say - a review?
I'm at best a demi-vegetarian, but I regularly dine with vegans and am well versed in vegetarian and vegan cooking. There are many vastly superior options in Montreal. Please check out my list of Veggies goodness for a better alternative,
