The King's Road, London. I used to ride down it every evening on my motorbike on my way home, crossing the Thames at Putney to join the A3. Ah memories. To be fair I didn't really ever pay much attention to what was alongside the road. It was just one of those parts of London with especially oblivious pedestrians who never looked before walking out into the road.
But apparently it's one of the top shopping destinations in the capital. Currently, a fairly substantial percentage of those flashy boutique shops are vacant.
