I have been to the Oxford Street area more times that it is probably healthy this week, I have therefore grasped a good idea of the different area Christmas lights. Carnaby Street are my favourite - they have gone for mistletoe and Holly and it works really well in the setting
Oxford Street have gone for presents and umbrellas (no, I didn't get it either...) but they do look nice. Regent Street have Arthur Christmas.
A couple more that made me smile..
