How long are you going for? It is such a wonderful city. We packed a lot in our time there Tower of London, Tower Bridge, Churchill War Rooms, changing of the guard at Buckingham Palace, The Royal Mews, Westminster Abbey, V&A Museum, went on the London Eye, took the boat to Greenwich, did the Harry Potter Studios Tour plus went to Windsor Castle and Hampton Court Palace. Also visited Harrod’s where we had dinner and had a meal at Hard Rock Cafe. We try to get to one if a city has it. We also had dinner at a restaurant in Piccadilly Circus. We are big zoo people so went to the London Zoo and also nearby the wax museum. I might have forgotten something.
