[duplicate of an equally-applicable review I wrote for the Costco Food Court at the Scarborough location on Warden].
Poutine is absolute best value in Toronto (in ANY food category): huge portion, under $5, and most importantly authentic (squeaky curds imported from Quebec) and delicious. Hot dog and a pop for $1.50 also a deal, but $3 for a slice of pizza is a bit of a rip.
