This original restaurant stands in an old "Breguet-2-Ponts" plane (a 2 stories plane) which flew daily in the 50's between Paris, Marseille and Alger.
A very nice traditional french cooking place located in S-E of Paris at Fontenay-Trésigny (halfway between Disneyland and Vaux-le-Vicomte).
A castle here ? No longer since that Louis XIV (the "sun king") decided to destruct this castle to conquere the city of nice in 1706. Nowdays it is a romantic parc from where you can have a view on nice town.
