This bakery is located in the CN building in the food court. If you are entering from the Rue de la Gauchetière, across the street from bon aventure, the bakery is located at the back left hand side of the food court. It's also right next to the entrance that connects from place ville marie.
Don't walk around the block looking for it. Like I did :(
I got a few goodies from this bakery as I love baked goods.
I didn't know what to expect when I went here but they had a pretty good selection from snacks, sandwiches to cakes and loafs of bread. Everything I got was pretty delicious.
