No, we have no idea either!

We drove out the other side of Cognac today for the RAF Association Christmas lunch. (For those who live in these parts, it was at the restaurant of the lady who writes recipes in the free 'Living' magazine)
This contraption was above the door in the barn restaurant. We had a very nice time and the food was good but disappointingly unChristmassy, apart from a mini mince pie at the end.
