France has three spots to eat
There is a "cafe" style around the back where you can sit and have a simple sandwich and fantastic dessert
The dining on the ground floor is much more casual compared to the one upstairs. We have eaten at both multiple times and the food is fantastic at both.
I would recommend the downstairs, ground level eatery. Try and make your reservations just before Illuminations, on a nice night they open all of the windows and you can enjoy the fireworks right from your seat.
