Christmas in Ft.Lauderdale
The best place (although expensive) is the Ritz Carlton (formerly the St. Regis) on Fort Lauderdale beach. They have a great brunch for $65 per person which includes a huge selection and all you can drink Champagne / Bloody Mary's.
They always have a ton of stations which are prepared amazingly -- fish, meats, omelets, deserts, pastries, etc. Last Christmas they even had fresh Stone Crab claws.
