L'Espèce d'Andouille is a French restaurant in Quahog.
In "Tiegs for Two", Quagmire and Brian eat there with their respective dates Jillian and Cheryl Tiegs until they start arguing, and the girls leave them behind. Outside the restaurant, Brian tries to make up with Quagmire, who pretends to agree but hits him with his car while leaving.
Its name is a common French insult, which translates roughly into "the stupid fool".
