Time Out says
Lady M is so popular right now that it recently opened its fifth branch at the airport. Nothing screams jet-setter than indulging in a variety of sweet cakes before boarding your next flight. Customers can also get their hands on their frozen Mille Crêpes cakes, which is sold exclusively at the airport shop, to snack on the plane. Each frozen cake is individually sealed, comes with insulation bags and an appropriate amount of dry ice, so you can take it for both long-haul and short-haul flights, and tuck in once it’s thawed.
