There is no children's menu. The normal menu is $125 plus gratuity and tax. Of course, alcoholic beverages and some items (fois gras, Kobd Beef, Iranian Caviar) do also cost extra.
Don't all small children love Iranian caviar and fois gras? Not to mention some of the other items from one of their dining experiences (yes, I know they change ... but they're certainly not offering pizza, chicken nuggets and mac & cheese!):
Seared Colorado Buffalo Tenderloin, Braised Fennel, Radishes and Blood Orange Vinaigrette

Borsao Tres Picos Garnacha,
Pondichery Peppered Quail with a Four Grain Pancake, Georgia Peaches and Corn

Not to mention all the wines that each menu item is paired with. Yeah -- like my 6 yo would've eaten ANYTHING off that menu. Nothing vaguely resembles pizza, chicken nuggets or mac & cheese.
Tell me honestly that you have a five year old child who can quietly sit through a 2½ hour dinner without disturbing any other guests in the restaurant, and I will turn you into Child Protective Services for keeping your child drugged.

Maybe w/all the wine pairings, the kiddies just get so drunk that they pass out in their plates!?!?
