I prefer buffet also. Bobcat is a picky-picky-picky eater. (Seriously, food can't touch and no sauces on the plate -- unless he put it there. ) So having a variety of options is wonderful.

If they decide buffet -- and have 110 people -- recommend they don't set up the buffet against a wall so that folks have to go by single file. If they pull it out some, people can form a line on each side -- much better for guests.
