A lot of Italian restaurant in the list , I am not surprised.
However most of them (e.g. Bocca di Lupo) are not genuine Italian restaurants. The chef is not Italian, the receipes are modified and (sorry to say so) the quality is average for any Italian who had the bad idea to go to those restaurants (like me).
Overpriced non-genuine Italian food, this describes 80% of the posh or famous Italian restaurants in London.
