the breakfast pizza at wolgang's is awesome. as far as tradition italian pizza, i wouldn't order it in wdw. When in Maryland have crabs, Maine have lobster, the west have beef, NY have pizza, but pizza in Florida just doesn't sound very good.
Anyway it is probably way too expensive for what I consider bad frozen pizza spend your money more wisely and go for something different......try some type of specialty at Epcot...enoy!
