I used to work at Domino's.  It's a classic American Pizza chain.  Although pizza was invented in Naples.
I would have eaten so much pizza. Ive heard of something called Neapolitan pizza. Is that something different?
Indeed it is.  It's a form of pizza made specifically with Tomatoes and Mozzarella Cheese.
I would love to go to Naples and eat some authentic Neapolitan pizza. 
Me too.  It's actually a bigger city than I thought.  Over 3 million people!  It's actually the 9th most populated city in the EU.
