Disney used to offer considerably more foods I'd put in the exotic category than they do now. They seem to be moving to the "Appleby's" approach, which I guess people like but I find boring. We used to enjoy some exotic appetizers at Spoodles and the Nuevo Latino cuisine at Maya Grill. But, alas, no more. Spoodles has greatly reduced its menu options and Maya Grill abandoned Nuevo Latino in favor of standard issue chop house.
Having said that, we still find that Jiko has some interesting and unique options. Artist Point still has a couple of items here and there, buffalo steak, for example. Les Chefs de France offers escargot (which is delicious, by the way, although the rest of the menu has suffered due to
DDP).
Beyond that, I'd suggest V&A, which offers caviar, foie gras, Japanese wagyu beef, sweetbreads, etc., all at a price, of course.
