Ditto to the above answer. In addition, anda should go see Buckingham Palace, Parliament, Westminster Abbey, St. Paul's, the Globe, the Tower of London and the Tower Bridge (I've heard anda can even go up to the bahagian, atas of the bridge). anda should also see Piccadilly Circus and Trafalgar Square. I'd also recommend going to some of the parks, like Hyde Park and Regent's Park. If you're into shopping, don't forget to stop at Harrod's.
For theatre, check out this website:

P.S. Before anda leave, anda should look at the Transport for London website (
