What meal were you thinking of - lunch or dinner? If you just want something small for lunch, like a piece of quiche or a ham and cheese croissant, then the bakery has those items, but that is about the extent of their menu besides pastries and that is the only counter service restaurant in France. I think Chefs de France has those items on their lunch menu, but there is also much more. The dinner menu is very nice, with Filet mignon and duck among the choices. It sounds to me like your mother would like a sit down meal in a french restaurant, but I think you should ask her more about what she would like before you decide.
