We have been La Fabrique once in 2012 and once 2013 while visiting Montreal for a long weekend. Both times the service was excellent and the food was amazing.
The most recent time we were there we stuck with a combination of small plates. They start with bread and their own pickles. I don't know what it is with those pickles, but it's hard to stop eating them. The beet/cheddar/pear salad was right on the point. We also had the mi-figue and the potato apple gnocchi as well as the foie gras torchon. They were all excellent. I would definitely recommend something that involves foie gras.
I used to be a vegetarian, so I tend to take a look at the menu with a vegetarian's eye. I think a vegetarian could also have an amazing meal here.
Staff was very friendly and attentive without crowding us.
