The London Underground is the quickest and easiest way of travelling around London.  London taxis are world renowned, drivers will give you local travel advice and tips – plus some banter; ‘you’ll never guess who I had in the back of my cab last week’!  Buses are the cheapest mode of travel and, with a seat on the top deck, very popular with families.  And the river bus will get you to a variety of destinations along the River Thames – a mini-cruise in town!
