I think they've done the pizza window by via Napoli off and on in the past, but hopefully this one stays.
At first I thought the prices on the menu were high but then the pictures of the slices actually look pretty darn big. And good! Ill.try it next time we go for sure. I for one welcome by slice pizza at Epcot!!!
