I adore Tim Horton's iced cappuccinos with chocolate milk, but I don't really see them as the embodiment of Canadian cuisine. I obviously see them as "the coffee shop with my favorite frozen coffee beverages."
Vernon, CT Timmy's, baby! Plus the one in College Park in Toronto.
I also had poutine once, and it's my "favorite food that I can never eat again." It was delicious, but my cholesterol is 147 and I want to keep it that way.
