Although expensive, taxis can be a very useful way to get about town. Black-cab drivers can be hailed on the street and are both generally very honest and extremely knowledgable: they know precisely where they are going, though they can talk the hind leg off a donkey.
The black cab is as much a feature of the London cityscape as the red double-decker bus. Licensed black cab drivers have the 'Knowledge’, acquired after rigorous training and a series of exams. They are supposed to know 25,000 streets within a 6-mile radius of Charing Cross/Trafalgar Sq and the 100 most-visited spots of the moment, including clubs and restaurants.
ComCab operates one of the largest fleets of black cabs in town.
