Galeries du Parc is so convenient if you're working or going to school nearby. I mean sure it's not a fancy place and it looks really depressing because of the layout and styling, but it has everything you need. It connects the Air Transat tower all the way to the Parc Cinema. They also do their best at having a varied food court. And if there's anything you feel like eating that isn't there, it is probably on parc street outside.
They have a postal office, parking, pharmacy, grocery store.
Also a Saint Hubert Express!
Obviously not somewhere you have to visit or should ever feel inclined to visit because it isn't anything special. But for people nearby, it's great!
