So I have 1 other day for the city of Naples. There seems to be a number of things to visit:
Teatro San Carlo
San Francesco di Paola
San Gregorio Armeno
San Domenico Maggiore
I suspect Castel dell'Ovo and Duomo is a must see - what're other sights that is unique to Naples?
Also, I'm a food lover - so any recommendations on local delicacy is very much welcome!
