Crazy Buffet.

Yes, it sounds like a cheap chinese buffet dive. However, this is a bit more upscale. (and the prices reflect that).
There are several. I know of one each in Orlando, West Palm Beach and Tampa. There may be others.
There is all you can eat sushi AND sashimi (50 varieties), with several (8?) sushi chefs constantly renewing the supply from behind the table. we're not talking huge rice balls with a little bit of fish, either, but Huge rolls and plenty of fish. The pictures on the website are accurate.
Add a mongolian BBQ, usually Peking duck, too.
Add 5-6 tables of decent to good Chinese food
Add a seafood table with crab legs, shrimp, oysters, mussels, etc.
Don't forget the soup table, at least three or more available
Add a salad table, including decent Kim-chi.
Add two dessert tables. The one in Orlando has a chocolate fountain. There are cakes, pies, and much more than the usual sad dry pastries at most chinese buffets. I remember rich strawberry cheesecake, chocolate torte, etc.
Oh, and an ice cream table (lots of tables!)
Granted, lunch was something like $17 pp, and dinner closer to $25, but that isn't out of line for a good dinner.
It's definitely worth a try!
