For the sake of discussion ONLY, you could go the Chinese route and look for shark fin and other rare products (go to Chinese medicine stores), fruits like Durian (available frozen at Chinese markets), fowl like pigeon or something that would be close to Ortolan, vegetables like water spinach (which is banned in some states because it's considered a noxious weed - and a DELICIOUS one at that!), raw milk cheeses and certain cured meats, and, of course, caviar.
Or, just say F it and do 7 courses of foie gras with lots of Alsatian and German Rieslings and Gewurztraminers.
