From what I've seen so far the buffet is divided into sections so I'll probably skip many of them & head right to the Italian area. we usually are the first to arrive for lunch & dinner so that may solve many of the seating problems.
I have hear people say the the self service drinks are not available (as a second thought) so it might not still be as bad if you can't find a server.
I suppose it is more sanatory to have them serve all the food although I do prefer to serve myself & take as much or little as I want. If they do that with the mixed salad it's something I'll skip altogether as I only prefer to select what I want, not what they decide to pick.
If they load up to much of a particular item I can always dump it.
