I once worked as a waiter at a restaurant that specialized in prime rib. They had 3 sizes. I don't remember what the other two were, but the largest one was 32 oz. That's obscene. 5 oz is a healthy portion of meat. But it was a matter of pride for the men to order the 32 oz cut and try to finish it all. Of course, in order to do that they didn't touch the baked potato or salad.
