Michael Portillo visits several of London's most famous locations, beginning on the South Bank, where the 1951 Festival of Britain drew more than eight and a half million visitors to admire fantastical buildings designed to inspire and celebrate the best of British in art, science and industry. After a spin on the London Eye, built to celebrate the millennium, Michael takes the London Underground to Chelsea to find out about Elizabeth David, one of the most influential cookery writers of the 20th century, and also heads to Covent Garden and Regent's Park.
