I definitely agree that there is a large amount of ‘what you grew up with’ being a key factor in expectations, which goes hand-in-hand with regional preferences.
My voter was for ‘other’, and I had two places in mind, one is for the ‘fast food’ category and one in the ‘sit down’ but not expensive category. And I don’t have any attraction to ‘gourmet’ burgers that cost $20+ and have things like truffle oil or gold foil
For Fast food, my first love will always be Blake’s Lotaburger of New Mexico fame. For anyone who hasn’t been to NM, they’re about as common as a ‘second tier’ FF restaurant, so behind Burger King/McDonalds, but around the same as Wendys, a bit ahead of Carl’s Junior franchises. They do ‘old fashioned’ burgers cooked from fresh on an actual griddle by guys in white paper hats. And the norm is green chile cheeseburgers, because, well, in NM, even McDs has GCC on the menu.
The ‘not fancy but not fast food’ choice is the Owl Cafe in Albuquerque (technically, the original in San Antonio NM is just as good, but it’s in the middle of nowhere) has one of the best green chile cheeseburgers in the state, thus the nation and therefore the world. What elevates it is the spices that are part of the handshaped, loose meat patty, along with everything else.
Sadly, I live @260 miles from the closest Lotaburger, and have for 2 decades. I normally only get one every other year or so if I drive to southern NM to visit family (@630 miles).
Of the voteable list, I have fondish memories of Whataburger, because when I worked 2pm-11pm many years ago, most places were closed (this was before extended hours at most McDs and Wendys and I’d rather not eat than have Taco Bell) but the 24/7 of Whataburger was there for me. It was never a favorite, but, it was there for me.
