Double Decker Bus
They were largely phased out in 2005, but you can still ride a red Routemaster double-decker bus on one of London Transport's (www.tfl.gov.uk) two heritage lines: No. 9 and No. 15. There's no tour (standard bus fare applies), but they pass landmarks like Trafalgar Square and Hyde Park.
Go to the gallery to catch everything from video projections to experimental works combining sculpture, sound, and light. Its summer pavilion in Hyde Park, with daring temporary structures commissioned from names like Rem Koolhaas, Oscar Niemeyer, and Zaha Hadid, is a highly anticipated annual event.
