Touted as serving up some of the best Italian food in Europe outside Italy, this superstar restaurant started a trend with its single-estate olive oils and simple roasts and pastas. Chefs Rose Gray and Ruth Rogers believe in using fresh ingredients, so you get salmon with Sicilian lemons, Tuscan bread soup with cavolo nero (black leaf cabbage) and Swiss chard -- plus one of London's highest checks. But remember, if you snag a reservation: this is in distant Hammersmith, and you can be stranded if you haven't booked a cab. Reservations essential. Tube: Hammersmith.
