I live in Bedford which has a large Italian population and so good pizza is easy to come by. The oddest sight is probably the Pizza Express; you look at it among all the authentic family-run Neapolitan pizzerias and bakeries and just wonder why they bothered sticking a pizza chain restaurant in this of all towns.
I love a capricciosa/valentino (ham, mushroom, olive) and a fiorentina (spinach with an egg on top), but really if the pizza is well-made and of good quality then you can't really beat a margherita. There's a little bakery near where I live that supplies all the restaurants and markets with bread during the day, and then makes pizzas in the evening, and their margherita is so good that putting toppings on it just spoils it.
I used to travel to Naples a lot and one time my friends there took me to what is considered the best pizzeria in Naples. One thing that struck me was that their calzone - which in this country is usually just a pizza folded over - was fried. Bloody delicious it was, too.
Wasnt called De'figiole by any chance was it?....
