There is no cloakroom at the Zénith.
If you bring a jacket, sweater or small bag, you will be able to keep them with you or place them on your seat.
Suitcases and other types of luggage will not be allowed in the Zénith.
Bottles are not permitted inside the Zénith: water dispensers with cups will be available; you may, of course, bring your own water flask to fill up on site.
