I visited this place with my best friend when we went to Montreal. We arrived early for lunch when the placed just opened for the day.
It was a no brainer that my best friend and I were not from Montreal. Our server patiently explained how the menu works - you can select a poutine from the "pre designed" list, or you can create your own. Amazing concept and I have to admit, it was fun picking your own ingredients for the poutine.
Food took a while to come, but the portion was massive. I was only able to finish 60% of it.
It was loaded with all the goodness I wanted in my poutine, but I felt like there was something special/unique missing in the food for me to come back again.
