I'm looking for a tip for a February Sunday dinner in Naples. We'll be staying in the Palazzo Decumani hotel in the center and would prefer to walk to dinner and back, about 10-15 minutes walk is fine. So something in the centro storico? It shouldn't be pizza as we'll be having that for lunch (need a quick lunch that day). We love fish but we haven't been south of Rome yet, so anything typically Neapolitan would do, in an informal setting (trattoria, not fancy restaurant). Any price is fine though. Thank you!
