Rated by many as quite one of the finest - but possibly least well known - restaurants in London. One-O-One is situated in Knightsbridge on the ground floor of the Sheraton Park Tower Hotel with a wonderful view of the passing shoppers through the wide windows. Specialising in seafood, produced with a real love of his subject by top chef Pascal Proyart, the choice varies from the incredibly simple, like poached lobster or oysters, through to the sublime.

It has picked up innumerable awards and is rated highly by all the major restaurant guides; little wonder with dishes like Brittany-style soupe de poisons, rouille croutons and Gruyere cheese or seaweed-steamed langoustines with wasabi-lime mayonnaise to start, followed by roasted wild sea bass, soft tapenade crust, grilled baby artichoke, purple crushed potato and parsley barigoule sauce.
