I always try to order something I've never seen before, even though I think I'll know what it is.
Last night I was at Fremont Diner, and ordered Hot Guts - which are Texas-style sausages - *very* spicy, with no beating-around-the-bush about what they contain. Also, they have a serious S-n-a-p followed by a torrent of spicy liquid accompanying the "guts" when you bite into them.
They were served on a plate, accompanied by plain, white bread, house-made pickles, and raw onion. These things define "indigestion," so unless you have a cast-iron stomach, they aren't what you want to play with.
(Not surprisingly, Fremont Diner also serves Nashville Hot Chicken with "no take-backs.")
