We decided to have lunch in the Orangerie, the gourmet restaurant for Chenonceau. It overlooks the Green Garden designed by Bernard Palissy and is located behind the old stables or Building of the Domes. The Green Garden is beautiful and the whole setting is serene and quiet. They also have a tea room open every day from 3 pm to 5 pm. There is a take-away restaurant in the old stables or Building of the Domes, but I don't know why you would eat there, the gourmet restaurant is very affordable and the setting is memorably beautiful.
