This is what people who eat meat assume vegetarian food tastes like. Bland, bland, blech.
Disclosure: I'm an omnivore with a vegan brother. I enjoy good charcuterie, but I will throw down for a plate of well-prepared vegetables. And at Le Commensal you will find neither.
If you want delicious vegetarian, head to Aux Vivres on Saint-Laurent. You will spend about the same amount of money and be significantly more satisfied.
