Fort Lauderdale Brunch
If money isnt an option the St. Regis on Fort Lauderdale beach has the best brunch that I've found. For $65 per person you get all you can drink / eat - they have a champagne / bloody mary station where you can get drinks as well as numerous stations set up with pastries, shrimp/seafood, omelets, deserts, pretty much anything you can think of. I went on Christmas morning and they even had fresh stone crab claws at the buffet... really one of the best.
The River House is excellent. We have been many times. If you go make a reservation for outside. Here is the web address. http://www.ftlauderdaleriverhouse.com/
We also enjoy Blue Moon and there are many choices other than fish and seafood. You can't go wrong with either place. I also read that Pier 66 has started a Sunday brunch at the top of the hotel. Might be worth checking out.
