Lacroix

Lacroix, the fine-dining restaurant in the Rittenhouse Hotel, serves a standard—and delicious—breakfast menu daily, but the Sunday brunch buffet is unlike anything else in the city. The utterly decadent all-you-can-eat spread includes everything from hand-carved Scottish salmon and wagyu brisket to sushi maki and oysters on the half shell. Of course, if you’re looking for pancakes and scrambled eggs, they’ve got those, too. The meal will run you $75 per person (plus drinks), but you have two hours of eating time to make it worth your while.
