Which differences were there between rich class, middle class and poor class dining in the Roman Empire?

by Chootwice

Obviously there was a big difference between the amounts of food. But what else was different between the two? I'm talking like ceremonies before dining, or the amount of people dining at the same time in the same room, the reason of dining, etc.

Are you talking about the Plebians, Equeatrians, and Patricians?
