Inspirational ideas for what to do in the capital, all of them costing
£10 or less - with many costing nothing at all. Enjoy big club nights
of little-known river walks; try martial arts or hula hooping; play
bike polo or hunt for classic vintage couture; drink quality champagne
or hear world-class music. From once-in-a-lifetime experiences to
everyday pleasures, there's always more to be discovered, without
breaking the bank.
