^ I really liked the one at La Belle Patatae! Their beastly looking smoked meat sandwich was really tender and delicious too!
I've also had the one at Fritz before too but that was a while ago, if memory serves me correctly it was pretty darn good too (although I was drunk out of my mind at the time lol)
I haven't tried Belgium Fries yet but I plan to in the very near future!
BK would be my choice if I had an instant urge and I'm not in downtown!... it ain't the best but it'll suppress my craving for the meantime!
Costco Poutine was mega-fail compared to any of the above!
