The location was hard to find for our two taxi drivers (we were in a party of six) but we got there eventually - if you are in a good hotel you might want to get them to book a hotel for you. The restaurant is away from the centre. But once we arrived everything was perfect. Decor is plain and there's no menu. We were told 25 Euros per head for meal or 30 Euros for meal with extra starter - cold crustaceans. We went for the 30 Euro option, and we found that this included wine, mineral water and limoncello and grappa and another liqueur afterwards. The food is amazing!!!! There was course after course, every course delicious, the fish really really fresh, the service excellent, the staff really friendly. Just writing about it makes me want to go back! If I go to Naples again (and I hope I will because I love Naples) I will definitely make a trip to Pescheria di Napoli.
