Footloose in London II: Undiscovered and Unusual

On a 2nd visit to their city, UK filmmakers Debra and David Rixon go off the tourist trail in search of new, hidden and quirky places to visit: Historic Fleet Street; a weird novelty arcade; an underground post train; 3 East End markets; posh shops in St James's; historic Docklands where the Mayflower set sail for America; lovely Hampstead; 300-years of tea at Twinings and the amazing Sky Garden.
