Not much really - this is the area where you wait when they take your luggage & passport when departing CDG. I've stopped here on LP to ORY transfers for a coffee, to use the loo/wash up etc. Can also use it on LP to train transfers that are not AIR & RAIL (for this you get access to the Salon.) For me, it feels like a better option for a conf call than jumping off a long haul into a car + CDG traffic.
