I can remember two dishes that blew my mind (I'm 41 and international) the first was a tomato sauce risotto that had the best beef I had ever eaten (coming from a French style food background) The way it felt and tasted was just amazing, until someone told me it wasn't beef but sea turtle meat, which was highly illegal but locals didn't give a fart. Wouldn't have eaten it had I known. Still, handsdown best meat ever. Second time was a kind of clear stock soup with a single floating slice of mushroom in Japan. I have no idea how they managed to squeeze so much taste and flavor out of water and mushrooms, but I ordered 2 more servings and ignored most of the main dish. The old lady owner was looking at me like I had lost my mind. They call it "o-suimono", it's just a side dish, often free with a course meal.
