This Winners is connected to downtown Montreal's underground city and is within Place Montreal Trust on the food court level.
I went here recently to purchase some sox for a Yelp Elite event (WeWork + Yelp Holiday Party) which were to be used as a donation for the homeless. I went to Winners the day before Black Friday at about 3:00pm and I found the place to be very busy. It was busier than I expected since it was after lunch and before 5:00pm. I picked up a bundle/package of 3 pairs of sox and went to the cash register.
There were many people in line at the cash register but the line seemed to go fast. There is one line and everyone lines there. Once one of the cashiers are free, the numbered light on the cash register will flash and a French message will indicate which cash register to go to.
I believe that at the time that I went, there were roughly 7 cashiers on duty and because there is only one line and people aren't picking which cashier to wait for, the line moved relatively fast.
I was satisfied with how my purchase went and for the price that I paid for my package of sox. I don't have any major complaints but there was also nothing exceptional about them so I gave them 4 stars.
