I have to admit this thread conjurs up all kinds of images in my mind. People actually go to these places for weddings?
I remember stopping at a Family Style Restaurant while on vacation in Pennsylvania where the buffet for children under a certain age was priced by weight of the children (there was a big scale in the lobby). They lost big-time on my grandson, but made it up on my granddaughter. I remember they posted something about not taking more than you can eat, which makes a lot of sense. I see so many people fill their plates high at a buffet and not finish half of it. That's such a waste.
When we go to a buffet, we usually get a little of everything we want, finish it, and maybe go back for a little of something we really liked if we still have room. Most buffets are still a bargain even if you don't go back for seconds.
