Chef Joël Robuchon employs his haute cuisine at two gorgeous, side-by-side restaurants. The less formal though still highly refined L'Atelier offers à la carte entrées plus a long list of small "tasting" portions that are whipped up in the central exhibition kitchen, with its gleaming, wraparound seating and startling organic flourishes. But it's the glamorous manse next door that has foodies buzzing. For the ultimate gastronomical rush, try the chef's 13-course, seasonal tasting menu—a waltz of rarefied creations, accented with sauces, froth, and froufrou, and costing $435 per person, sans wine. There are a number of smaller options, both in courses and price tag. This is one impressive operation and a fitting venue for a celebratory meal, though a few restaurants in town deliver nearly as splendid service and food.
