A cautionary tale. We are not suckers, but we were had over this time.
Castel dell'Ovo is surrounded by tourist-orientated restaurants, all at one another's throats. Oste Pazzo is not an exception. If you even glance at the menu board outside you are lured in by a glass of 'free' bubbly (but later the bill contains a 'Coperto' of course), and then your wallet is expertly filletted of its contents.
To be fair we did find a very decent bottle of Amarone lurking inside, and the price for that was reasonable at 50 euros. Otherwise some fairly ordinary fried fish stuff, one sweet, two coffees and one glass of Amaretto brought the whole bill up to 180.12 euros!
There are wonderful places to eat in Naples. Go and find one. If you are outside the Oste Pazzo you have not yet succeeded. We paid so that you can avoid having to do so....be grateful.
