Our family tried the one from Safeway years back (when I was a kid) and from what I can remember, it was decent.
Most recently though, we did the one from Sutton Place Hotel last year and that was really good. Although it's intended for 8-12 people and costs $325 + tax.

EDIT: I forgot to mention how easy the process was with Sutton Place Hotel. You order and pay ahead of time over the phone. Once you arrive at the hotel, you pull up front in a designated area, give them your name for the order, and they load everything into your vehicle.
