Guess what this is....!

A few clues......Mr C and I came up to Londinium today. We walked from Charing Cross, through Trafalgar Square, The Mall, Green Park and Hyde Park, to see The English National Ballet perform Romeo and Juliet at the Royal Albert Hall. We had one or two ciders on the way and were both a little tipsy - we don't get out much! Now we're heading back to see if Noo has been looking after his grandparents well....
