We stopped in here for lunch on a long weekend trip to Montreal. The food was pretty good,--I had a tuna salad sandwich, and my wife had a smoked turkey baguette.
On the other hand, the service was rather slow, and the price (about $30 for the two of us, with just the sandwiches and one Coke Diete) seemed pretty steep, especially compared to some of the other deals that we got in Montreal (better food, lower price at both Buvette Chez Simone and le Cartet).
It was a perfectly fine lunch spot, but not worth making a trip for, and nowhere near the best available that we experienced in our short time in the city.
