If you're curious I actually have the menus for all of the restaurants - and yes there is an $85 cheeseburger. Though the appetizer I find most outlandish is the prawns with apple and caviar for $350 at 1947, but I found dinner at the franchise in Courchevel quite disappointing so I don't think I'll be expecting too much from this one. The tasting menus at Diptyque do look very good and seem reasonable running between $240 to 410 per person. Probably not quite in the realm of Geranium but cheaper and better than Noma I'm hoping - time will tell...
