Does anyone know of any cheap, good restaurants in the Chenonceau or Athee-sur-Cher area - or within 20 minutes drive? We are coming down there (from our home in Brittany) for a few days at the end of June and as we only do 'casual' we are not looking for top-nosh eateries, just basic, good food! Also, is there anything that we really shouldn't miss whilst we are there? (not chateaux, we know that already!). Thanks in advance.
