I'm going to take a different turn on this, and tell you all of the unusual, or unique foods I have tried. MOST of which I like, LOL. MOST of us, I'm sure, can claim the enjoyment of many Italian, or French foods/dishes. So, stretching one's pallette, my favorite ethnic food genres are:
Indian, Filipino, Viet, Thai, & unusual Chinese things like hot-pot.
I have eaten Morroccan, Somali and Ethiopian african foods, Russian, German, British and Polish (lord I wish she had stayed in business) Euro-foods, Japanese, Cambodian & Korean Eastern foods, Lebanese, Iraqi & Syrian Middle Eastern foods. Greek/Middle Eastern is mostly, meh.
Sushi: Love anything rolled/mixed. Plain pieces of fish are simply boring.
Tripe: Fried Chitlin' style, in Mexican menudo soup, or crispy in soft tacos. Love it. Stewed southern style, meh.
Cow brains: Again in Mexi tacos. Similar in texture to fatty pork. Not bad, but not worth the risk again in my book (Google Krutzfeld-Jacob!)
Pig snout & ears: part of my fave Filipino dish called sisig (also w/liver) . I get the ears sliced and steamed(or wok'd?) w/hot spices in several asian places around town. Love it.
Scrapple: Yum, yum, and then sum. Thin and crispy, like hash.
Goat: the beef of the Middle East. Yummy. Roasted, or curried.
Lamb: even better
Pig blood: in a Filipino stew called dinuaguan. Like limburger cheese, it's an acquired taste.
Beef Tendon: the white cartilage kinda stuff. In Vietnamese pho soup, or sliced and steamed w/hot spices in several asian places around town.
Beef tar-tar: once, at a sushi joint. Swathed in hot-red-chili spices. LIttle goes a long way, like caviar. Take it or leave it.
Sqid and octopus: Fried and spicy, just fine. Mostly an Asian thing.
Rattlesnake, alligator: 6 of one, 1/2 doz of the other so far as taste. Enjoyable fried. Snake and gator have texture of lobster.
Frog's Legs: Really are like poultry/chicken. Enjoyable, but don't crave it.
Kimchi: The greener the better (as in more bok-choy)
Dried fish: little guys, like bait. In Korean red spice sauce, or crispy-fried and salted Filipino style
Ostrich: The 'beef' of the poultry community. Delicious.
Rabbit or venison: ONly tried as a kid, and I can't recall much.
Love all commonplace veggies especially fresh spinach, Brussells and asparagus.
Cauliflower is BEST reserved for an India dish called Gobi Manchurian, LOL.
DISLIKEs:
Canned Veggies, with asparagus and spinach the top-two offenders. Only could eat either chopped up in a soup.
Hates:
Beets, rhubarb, most radishes, durian,
