If you're saying "Foie-WHAT?" after reading the headline, you've probably never eaten the French delicacy that is Foie Gras.  Essentially goose liver fat, the food is often used as a luxury ingredient at restaurants that serve haute cuisine or by itself as an appetizer.  It's also been banned by the State of California because of the way that some geese are specially-raised to harvest its liver fat.  (Like much of the food you eat, you probably don't want to know any of the details.)

The ban has caused high-end restaurants and their customers to bemoan the fact that one of their favorite foods is no longer legal in California.

Now a San Francisco restaurant believes that they've found a way around the law.  The Presidio Social Club claims that they're exempt from the law due to their location - on Federal land.

Restaurant owner Ray Tang said that since his business is in the Presidio National Park, he isn't required to adhere to the state rule.

While customers have rejoiced at the news, supporters of the ban aren't.

"If Presidio Social Club keeps going down this road, this will be a battle for the lawyers for certain," People for the Ethical Treatment of Animals spokeswoman Lindsay Rajt told HuffPost. PETA has been one of the most vocal advocates of the ban.

"It's upsetting to see businesses trying to exploit loopholes, and you can bet that protesters will be picketing and showing footage outside their doors," she vowed.

Now, other restaurants are exploring their options and it looks like the battle is far from over.
