Foie gras is a dish made up of fattened duck liver. There's a controversy around it because in France, the ducks are reportedly force-fed corn to fatten their livers. Because of this, a group of protesters set up shop outside of Chef Ludo Lefebvre's touring restaurant on the latest 'Ludo Bites America' (Tue., 9PM ET on Sundance).

When he found out they were out there, with signs protesting the cruel treatment of ducks to make the dish, he shouted to them through the windows.

"That's too bad for you!" he shouted. "I'm serving a lot of foie gras tonight."

He explained in a confessional that the farm he uses doesn't abuse any animals, but he didn't bother to tell that to the protesters. Likely, they wouldn't have believed him anyway.

Unfortunately for them, though, the protest drew attention to the dish, and many patrons ordered it solely based on the protesters.
