This place has great pizza, and I love it for lunch or an early dinner. But for breakfast, if it's open at all, it's probably going to have the usual fare. I'd just grab a CS breakfast at the resort, and save Pizzafari for a lunch. We love this place because the pizza's good and it's somehow never as crowded for us as most of the other CS places.
But if you spend time eating your breakfast here, you would not be getting anything you couldn't get at your resort, plus you'd be spending time you could be spending riding a popular ride or getting fastpasses.
