They have a more private area separated by a wall with open windows into the rest of the seating area. There are drink machines and a smaller serving area within the room or guests can simply visit the normal buffet line.
Jonathan is right. However, if you're looking for a private area this will really not work unless you are the only ones in the room (which is about the size of the rest of the dining area). It is a nice area when I've been there that is the area I would prefer to sit, but it is again, not necessarily private.
