Middle of the road thrift store.
On one hand they have really great selection. But, am I interested to pay 150$ for a vintage dress because it's vintage silk...Maybe not.
If you are grossed out by places like "village des valeurs" and renaissances. It's a great place for you since all the good stuff is already skimmed out. In fact, there is a few stores like this one almost neighbouring each other so if you want the full experience. Look around on Saint-Laurent.
This is a great place for a stop.
