You can obviously also reach the restaurant using the public transport. The next stop is SNCF-Rambouillet, 366 meters away from Ishii, otherwise, there are places to park 40 meters away at Place Félix Faure.
As soon as we have a menu from Rambouillet for Ishii, we will publish it here. In the meantime, feel free to check out the menus in the area.
