Went to the source as in Italy or an Italian joint in Aus?
As with everything, one place can do things amazingly where 100 others fail. Not that I've been to Italy but I'd imagine their product is a bit more consistent between restaurants?
Provided you use good quality, fresh ingredients and plenty of seasoning, there's no reason it can't be tasty, even if there isn't 10 different toppings on the thing. Simple can still be flavoursome....but that said, I'm quite happy with a loaded supreme or meat lovers!
