Cheese, fries and gravy. A classic trio that when combined, creates a mouthwatering dish we all know and love as poutine. Now, grabbing the iconic Quebec meal at one of Montreal's must-try spots is how to really do poutine right. But sometimes, a poutine from one of the big fast-food chains just has to do. I put four chains to the test: McDonald's, Harvey's, A&W and Wendy's to find out which was the most delish dish and when it came to this motley crew of poutine, it was clear that one fast food spot was easily the standout.
