Give them a try. They have a location in Oakville. Their pizza isn't quite the same as PizzaHut but it's really good. Their pasta is their strong point. Try the Fettucini Alfredo.
As for the best Pizza i've ever had it would be from a place called Vesuvios. Used to on Jane Street in Toronto. Don't know if it is still there or not.
