The Supreme Foie Gras burger features diced foie gras sourced from France, a 150g (a bit more than a quarter pound) grilled beef patty, caramelized onions, and arugula and will be served in a fancy-looking black paper clamshell.
The sandwich alone is priced at 5 euros (~$6.49) or as part of a set for 7.50 euros (~$9.73).

Foie gras (literally "fat liver" in French) is made from fattened duck or goose liver. It is a popular delicacy in French cuisine but is also controversial due to the force feeding procedure used to fatten the birds.
