<strong>Marcus Wareing at The Berkeley</strong><br />Wareing broke loose of his boss Gordon Ramsay earlier last year and since then, his double Michelin-starred restaurant has been a major draw. It is critically adored for its innovative food and elegant d&eacute;cor and service. Stand-out dishes include a 24-hour cooked Welsh suckling pig with chicory.

Its old-world opulence sits perfectly within the venerable hotel &ndash; as do its hearty dishes, such as Highland venison Wellington with smoked potato pur&eacute;e.

The dining room is stylish and plush, the service perhaps a bit over-attentive, and the food utterly delightful &ndash; die-hard French with Asian accents. Carlos Place, W1K 2AL, tel: 020 7499 7070.
