In 1742, George William Wilton set up a stall selling oysters, shrimps and cockles close to Haymarket. This year, its descendant Wiltons restaurant celebrates its 280th anniversary as London’s favourite fine dining establishment. To mark the anniversary, a seven-course menu will be served from 1 July until 31 August (available for dinner only) at £280 per person, including wine, water, and service.
