is there any differences between american pizza and italian pizza?

They are extremely different! If an Italian pizzaiolo prepares a pizza in US, then he might well make an Italian one rather than an American one. Italian pizza is flatter, thinner and once you have tasted the 'real' thing, it is difficult to go back to eating others www.lifeinitaly.com/food/pizza-history.asp

hi frnd.. nice question to be asked. i like both pizza if my friend pay for that two. happy eating.

Italian pizza is definitely thinner as compared to American pizza. But I do love them both. However, I think everyone knows that pizza originated in Italy and of course they I love to eat Italian pizza over American pizza. But for as long as its a pizza, I do take it considering that I am a pizza lover.

I've seen this on several food shows. Allegedly, the first original style pizza is very similar to a Margherita pizza (tomatoes toppled with mozzarella slices and basil leaves on a thin crust) that is cooked near a wood fire. The Chicago deep dish pizza is supposedly a "bad" impostor, though more filling and tasty due to the layers of ingredients. Domino's, Pizza Hut and even Papa Johns are considered American pizza for their use of mozzarella blend cheeses and non-traditional ingredients like poultry, barbecue sauce, nuts and other things that seem foreign (and possibly insulting) to most Italian cooks.

i dont know whats the difference between american and italian pizza. as for me as long as its pizza and it taste good then it really doesnt matter to me what it called. though my favorite is supreme pizza coz everything is already there. and also vegetarian pizza. though i always have a free hawaian pizza the same size as what i order every time i order since i have a membership card from the store where i bought the pizza.

Italian pizza is thinner and usually have less stuff on it, maybe just pizza sauce and cheese, sometimes one extra topping. American pizza usually is quite thick with lots of stuff on it. I've had some good pizzas in Italy but also some very weird ones. My friend ordered an vegetarian one and instead of just giving her a Margaritha she got the left overs from some other vegetarian meal on it, one piece of carrot, one piece of potato, one piece of broccoli etc.
