Good article.
I have to disagree with where you can find the best pizza, but I have not tried them all by any means.
Da Dora is a terrific restaurant and I don't think that I have been to Naples without eating there. The fish is exceptionally fresh and simply prepared.
For me, Ciro a Mergellina is another shouldn't be missed restaurant. They have the best mozzarella that I have ever had. It is not even similar to what we have here.
