Head for central London and then take a bus, any double decker, head for the top deck and sit at the front. You'll see the intricacies of London architecture and street life that you wouldn't see at any other angle. I've heard that these buses are being phased out which is a huge shame. So do it now while you have the chance.
Number 73 is a great route for this...Send your feedback or queries to been.there@guardian.co.uk
