One of the few (VERY few) good things about the West Island.
If it's summer and you're on the highway and craving something cool, take a small detour off the 20 and go to either location in Dorval village or Pointe-Claire village for some great home-made ice cream.
With some creative flavors like Elephantastic (Choco-Peanut Butter), Guiness ice cream, and the creamiest Green Tea ice cream I've ever come across in Montreal, Wild Willy's is the rest stop of choice for the summer months.
When I used to live in Pointe-Claire, many a summer's afternoon was spent with a waffle cone of Green tea ice cream in one hand while strolling along the Lakeshore and taking in the lake and the sunshine.
