I think the phrase "a conglomerate of Roast of Beef Feast" alone makes this contest-worthy. As for the corn, potatoes, and possibly the bananas being anachronistic, please note they do not say "Ancient" Roman.
Magic Time Machine is a chain of restaurants in Texas. It's still around and the Roman Orgy is still available. As long as I lived in Texas, I never got to eat there, sadly. Seems like every time I planned to go something would come up.
