fabulous CELEBRATORY restaurant in VEGAS for group of 20?

[foodseeker]

We are going to Las Vegas over Thanksgiving to celebrate an 80th birthday with a large group of family. Any suggestions for amazing places that would take a group of 20? Must be something special. . . any price range welcome. Also, we are staying on the strip.

Thanks in advance, Chowhounds!!

Picasso would be perfect and they handle parties of this size with ease. Wonderful setting with equally impressive food.
