Copperfield offers, in addition to a variety of seated menus, something called "Station Dining." I assumed this was the same thing as buffet, but I was wrong. I asked on two forums what the differences are and here is what I learned:
Station Dining is basically different tables set up in corners of the room, each station with a different type of food. Sometimes there is a chef preparing, finishing, or slicing the food right at that table. The benefit to having stations instead of a buffet is that people don't get backed up in a long line.
