Most of the things I've eaten (and would choose to eat again) aren't terribly odd. It turns out some ingredients pair well and others do not.
The oddest food I make and eat again (and it is only odd to people who have not tried it) is my own take on the classic Beer Bratwurst. I start by simmering the sausage in beer (which isn't strange in the slightest) and then finish the sausage on whatever cooking surface is available. The odd part is that I simmer in the heaviest stout I can find (one pint per five sausages). Upon removing the sausage, I reduce the stout and add various things to the eventually resulting a black ichor that clings to the onions and is more or less a somewhat sweetened stout concentrate. To this, I add a shot of IPA (largely for the aromas). Sausages are served stuffed into some sort of bun with a bit of Brie and then topped with the sauce coated onions.
The dish actually got it's start entirely by accident where leaving a burner on and attending to other things made me notice that stout (which was chosen because it was the beer on hand) combined with the onions, produced a thin syrup that even in the native state was pretty good. The recipe has morphed over the years I've made it to build a better topping. I've even leveraged this sauce into a custom sauce of various BBQ dishes which is a minor heresy given in Texas (where I live) dry rubs are king.
I have, however, eaten various foods of naked people before. Sushi is the only example where I've done it in public of course.
