Grant Achatz's buzzworthy sophomore effort is big on concept: the restaurant completely transforms itself every three months to focus on a unique theme. The opening menu, Paris 1906, paid homage to famed chef Auguste Escoffier's tenure at the Ritz Paris. Subsequent incarnations have pulled favorite hits from iconic restaurants or explored the future of Chinese cuisine. The tasting menu ranges in price from $70 to $485, depending on the date and time you book; tickets are paid for in advance, nonrefundable, and available only online—or via resale markets at highly inflated prices against season ticket holders. Tables accommodate two to four guests, with the exception of the six-person kitchen table.
