La Madeleine Grilled Chicken recipe?

Does anyone know the recipe for the grilled chicken that is used on the Ceasar Salade at La Madeleine restaurants? Is there a marinade or something? Please please please if you know someone who knows, works there, etc, ask them and post here! I can't find it anywhere on the web and alot of people have asked about it. You would make millions of friends after posting it!!!
