There seem to be a huge fanclub of this ice cream parlor - we had to wait for 20 minutes to get a serve of ice cream! On a weekday! We didn't go for soft serve, but for their traditional ice cream - peach (out of this world) and lemon praline (a bit disappointing).
It was our last day in Montreal, hence we spent all our remaining cash on this - I would have loved to have CAN$5 more just to try the strawberry / coconut soft serve, but nope. Not a single coin left. Poor me.
Also, please note that Yelp's (and Google's, for that matter) opening times are incorrect - we arrived just before 8, having run half of the way not to miss that, and it was still open after 10 when we left the restaurant we went to after. So don't panic and get there already :)
