Thought I'd bump this for a review on Western Pizza (used to be called "Tumblers" in Sasky)

A buddy of mine from Regina RAVES about this place. He says it's better than volos, which is impossible IMO, but I was down south in Cranston last night and gave it a shot.
My opinion? it's a good pie. Probably one of the better ones I've had in the city. Good crust, good ingredients, but the main problem was the size (15") which makes it hard to cook in the center without getting soggy. All in all though, it held up to my pizza snob pallet.
If you're close to one of their locations I'd give it a go, I wasn't overly disappointed.
