Dinner by Heston Blumenthal, a brown cavern in the Mandarin Oriental hotel, Knightsbridge, has won a second Michelin star. These stars are food ‘Oscars’ (Hollywood has eaten everything, despite its tendency to despise food) and ensure that wealthy Americans make a detour to dine beneath the stars. This new elevation means that Blumenthal, at least technically, is Britain’s finest cook; the Meryl Streep of dripping and sweat.
