How long to Picadilly?

I did not know they had a bus service from La Madeleine (in Paris) to Picadilly Circus (in London)?! I'm kidding, they don't! In fact several companies (like this one)rent out all sorts of weird vehicles - yes, for us French this is a "weird vehicle"! - on special occasions: weddings, promotional tours, etc. This makes me think that I haven't been to London in years, maybe they don't have these buses there anymore! Have a good weekend everyone.
