Duckeasy

A restaurant that surreptitiously serves foie gras (fattened duck liver) in jurisdictions that outlaw the practice. The name is a play on the prohibition era phenomenon of the speakeasy, which illegally served alcohol.

George: I'm going out for some foie gras tonight. Want to come?

Martin: I thought that foie gras had been banned.

George: It has been but you can still get it at the duckeasy.
