For a bird's-eye view of London, take a spin on the London Eye, the Ferris wheel overlooking the Thames. Don't miss landmarks like Big Ben, the Tower of London, St. Paul's Cathedral and the Globe Theatre. Spend a day at the Tate Modern or shopping along Portobello Road in Notting Hill. See the Cabinet War Rooms that housed Winston Churchill's WWII bunker and watch the changing of the guard at Buckingham Palace. Need a break? Have a pint in a pub or visit a famous London tea room.
