There is an amazing range of champagne related gift ideas. For around £15, you can have your name or a message printed on a label to create your very own personalised champagne. You can get these personalised bottles at a place called Champagne Sélection, opposite the entrance to the cathedral. The local speciality, biscuits roses, are made to be eaten with champagne. You can get them direct from the producer, Fossier, at 25 Cours Langlet, 100 metres or so north of the cathedral.
