If you haven't been, you must, I have been multiple times both to L'atalier and To this high indexing restaurant.
You won't find a better prepared team, and more tasteful menu, and a better ambiance in the world.
Serious diners only, bring your pocketbook, this is a World Class Dining experience.
I have done the tasting menu and have hosted a 14 course Krug dinner. All of the experiences I have had are top notch.
The bar at Roubochon, just off the entrance to the left is the best kept secret for an amazing cocktail in the US.
Bon appetit!
