An extravagant Sunday buffet brunch is the draw at this quintessential Old San Francisco restaurant, in the Palace Hotel. The choices seem endless, with everything from pancakes, omelets, and salads to roast beef, sushi, dim sum, and raw oysters available. In daytime, light splashes through the dining room's beautiful stained-glass ceiling and against the towering Ionic columns and crystal chandeliers. If you can't make it to the Palace for Sunday brunch, try the Saturday-afternoon high tea. Reservations essential. Jacket required.
