Pizza is one of my favorite foods.
Me too! Pizza is different all over the world. What type of pizza do you like best?
I like New York style pizza the best. What other types are there?
There are so many. lots more than I can name here. My favorite is probably Detroit style with a thick deep crust.
That sounds good. I have never heard of Detroit style pizza. Where was pizza created?
Pizza is traditionally an Italian dish from, surprisingly, Italy.
I would love to go there and eat pizza in Italy. Maybe Naples. 
Italian food is great. It has developed over the years by social and economic changes with its roots going back centuries.
