The run of the mill food-serving court is way better in Napoli or in other Mediterranean countries compared to the similar locations in London (or in other Northern big cities) for the simple reason that those Mediterranean locations have easier and cheaper access to fresher (and better) food.
Maybe some high-end London locations have the same easy access to fresh and better food (via dedicated airplane rides), but that does not make London one of "the food capitals of Europe".
