London transportation

The fastest way around London is by the tube. But you're underground, breathing foul air, herded like cattle at transfer stations. The most expensive is by taxi and it can be very expensive. The slowest is by bus. Yesterday, I had lunch with a friend in Belgravia. What a treat it was to walk down Sloane Street past the achingly beautiful and wildly expensive shops and then take the bus back to the flat in Maiden Lane. I sat on top in the corner and watched the world go by. We lumbered past Hyde Park Corner, the Wellington Arch, Green Park, the Ritz Hotel, up Piccadilly past the Royal Academy of Arts, around Trafalgar Square, up the Strand to Maiden Lane. A great way to see London and get home at the same time.
