As I once said it shocked me when I learnt that in America you guys are only offered PIECES of pizza.
In France when you order a pizza at a restaurant for yourself you get a whole one
People eat whole pizze here it's not uncommon at all and it's the norm
Families tend to divide up food and if you want a whole pizza to yourself, you usually end up buying it for yourself. Plus, I think buisnesses over here think they can make more selling individual slices. You can get a pizza for yourself, but it is few and far between in my experience.
Generally you'll get slices if it's from a fast food type place, but in actual sit down restaurants, you'll get a whole pizza of the size of your choice.
