then he asks
Fatted Calf has a terrine and a torchon on their list at the moment. Polarica has a large selection, including goose. So does Gourmet Corner in San Mateo.
You could also call Sonoma Artisan Foie Gras, Hudson Valley, and d'Artagnan and ask for local retailers.

re: Ruth Lafler
The definitely carry Grade A lobes of foie gras regularly. I have not seen terrine or "au torchon," though, but am not at all sure that they don't.
If OP is ever in Berkeley, Cafe Rouge has "au torchon" frequently. I happen not to have tried it but like all their charcuterie that I've tried. Fabrique Delices is decent.
