Sorbillo is one of the best place in Naplesw where to try the real neapolitan pizza. Sorbillo is one of the oldest neapolitan pizza family: Luigi had 21 children and everybody of them became pizzaiolo. Ask for Anna or Gino who run the pizzeria and you'll find the real neapolitan hosting. It is very busy during lunchtime and in the evening so they'll take your name and you'll have to wait outside, but it is worth it.
Its amazing the difference between the pizzas here and the UK. The ingredients are so fresh and the base is perfect.Highly recommended.
