Sbarro is good esp for mall food and this is a lot of experience as an Italian speaking. Lot of flavor, good cheese.
I used to eat Pizza Hut at the Wash. DC Amtrak station that was exactly like cardboard with grease added.
I have never had it, but I was raised in a dominantly Italian area.
I doubt it would pass my test based on commentary here.
Sbarro is often one of the better options at many airports. The cheese and sauce are not bad.
