French law historically tied casino licences to spa and resort towns and barred them from Paris, so the casino closest to the capital sits at Enghien-les-Bains, a thermal town on a lake fifteen kilometres north of the city and twenty minutes from the Gare du Nord by train.
It is consistently the highest-grossing casino in France, because it draws on the Paris metropolitan population without competing with a city-centre venue. The floor divides between a large machine hall and traditional tables, with a theatre and restaurants attached.
