We had a group of 9 (normally the maximum is 8 guests, but Gordon was nice enough to squeeze in an extra person for us!) at a "Private Affair" in July. It was a blast!
Gordon gives you many menu choices -- for the appetizer, entree, and dessert -- but I'm sure he would do a special request if you asked. The "sides" are usually based upon what you choose as your entree and what is in season.
The dinner is held at Signals, at the beach house -- since we had a beautiful evening, Gordon opened the large doors out to the deck, so we could feel the ocean breeze. It was fantastic!
If you can, do it!!!
