We'll be travelling in a genuine London Black Taxicab, driven by a London Cabbie—all of whom have had to go through the fiendishly difficult "Knowledge” of London. Not only do they know every street in London, but they also have to know every route between two points in the capital. London Cabbies also have to undertake a thorough background check. Only London buses and taxis are allowed to use the exclusive lanes throughout the city, which means that we can get around London much easier than most.
