I’m sorry that your Naples guide doesn’t include info about Italian cuisine, but let’s fix that! Here are some tips on restaurants and street food that you absolutely must try:
Top Restaurants (in my opinion!):
L’Antica Pizzeria da Michele: A classic! Only two pizzas: marinara and margherita. Essential, but unforgettable. Expect a bit of a wait, but it’s worth it!

Trattoria da Nennella: An institution in the heart of the Spanish Quarters. Super lively atmosphere, very low prices, and authentic Neapolitan cuisine. Perfect for an authentic experience.

Starita a Materdei: Another historic pizzeria, slightly out of the center, but famous for its fried pizza and more “creative” pizzas.

Amazing Street Food:
Friggitoria Vomero: For incredible Neapolitan fried food! Try the fried pizzette, arancini, and pasta frittatine. Perfect for a quick and tasty snack.

Tandem Ragù: If you want to try real Neapolitan ragù, this is the place to go. They serve it in a thousand different ways, including takeout.

Le Sfogliatelle Mary: You can’t leave Naples without tasting a sfogliatella! Mary is a guarantee; both the riccia and frolla are divine.

Extra Tips:
Don’t be afraid to get lost in the alleys and try the places that inspire you the most. Naples is full of culinary surprises!
Ask locals for advice; they are always ready to give a good suggestion.
Prepare your stomach because in Naples, you eat (and drink!) well!
I hope these tips are helpful! Enjoy your meal and have fun in Naples! 😉
