I had a bad experience at Brigitte's, both food and service-wise, so I wouldn't recommend it. You might want to check out Alexander's Steakhouse in Cupertino. Their steaks can be ordered topped with foie gras and they have a few small dishes that include foie gras.
When I went I had the lamb atop flageolet beans and the lamb was extremely dry and lacking in flavor even though I ordered it medium rare. Also, the beans were still crunchy. The service was wierd in a way that I won't get into here except by saying it was a little too "snooty".
