In Chinon we stayed at the Hotel de France a bit anonymous but very comfortable and friendly - and very close to the castle. We spent the morning on a trip around the castle - far older and more mediaevalthan the rest of the Loire. We say it from a distance on various trips past over the years so it was good to have a look around. Jeanne d'Arc met Charles VII here and it's also much associated with Henry II and Richard (of England).
For lunch we had sausage, cheese and wine(!) at La Cabane à Vin a very pleasant pavement cafe close to the main square had a restful afternoon and then ate at Le Gandoyau again much enjoyed.
