NO! NO! NO! NO!
I think most buffets are just plain nasty. I've worked at restaurants that did buffets (Friday night seafood and Sunday Brunch) and you don't want to know what happens in the kitchen. The smell of scrambled eggs in a steam tray literally makes me gag, even to this day 18 years later. Most buffets are large quantities of mediocre food. I would rather pay the same price for one plate of hot, fresh, cooked to order food than an all you can eat buffet. I need to watch my diet so try to go for quality over quantity.
my in-laws took us out to lunch on Mother's Day a few years ago. We went to a favorite restaurant, unfortunately the restaurant decided to do a special Mother's Day buffet and would not let me order off the menu. so I sat and chatted and drank an iced tea while every one else ate. I now offer to cook on Mother's Day and invite them over. I make a few things ahead of time, DH grills meat and it works.
there are exceptions of course, but they are few and far between. I LOVE the breakfast buffet at Paris in Las Vegas. But I get fresh cooked eggs and waffles and such which makes a huge difference.
