La Grande Arche de la Défense.

I think they only put out the big balls decoration for Christmas. It was very pretty. Behind the decorations, there is a Christmas market. Quite commercialize here, it's everywhere!! But it was this visit that makes me realize the key ingredient for a good vin chaud! Oranges! The seller in this market make a better vin chaud than the others that I've tried in Germany and other regions in France, so far.
