At this casual spot, superstar chef Thomas Keller offers a single, fixed-price menu ($52) nightly, with a small lineup of decadent brunch items served on Sunday. The dinner selection might include braised beef short ribs and creamy polenta, or a delicate panna cotta with a citrus glaze. The dining room is warmly low-key, with zinc-top tables, wine served in tumblers, and rock and jazz on the stereo. Call a day ahead to find out the next day's menu. From Thursday through Saturday, except in winter, you can pick up a boxed lunch to go—the buttermilk fried chicken one is delicious—at the on-site and aptly named Addendum.
