This is a repeat of similar info already posted elsewhere. ::)The ones you've picked are all very close together and IMO represent some of the best you will find.Although I haven't yet tried them all,the following should be searched out.The last one is a little out of the way from the others ,but is almost unanimously considered one of the best.It's at the top of my "next time" list.I've read mixed reviews elsewhere recently however.Decide for yourself.
Pizzeria Starita a Materdei
Via Materdei 27, 28, Naples
Of historic significance due to the Sophia Loren connection,but unlike some other famous places this one is said to live up to it's fine reputation.
VIA BERNINI 29
(Vomero - Metro Vanvitelli)
Different in character from all the others and perched high above Napoli as in heaven !
Largo Arso 10/16 - San Giorgio a Cremano
I would suggest that anyone going to Naples to look at a Map on-line,get the subway routes guide and plan out a trip accordingly.You can figure out opening times,proximity etc from that and the info posted on this forum.It will save you a lot of head scratching and wasted leg work when you get there.
