Specifically, the "Runza" itself (I think there are some other names for it like krautburger, or perhaps cabbage burgers like you're referencing?) I personally don't think they taste good, but, I primarily think they're unsophisticated, dull, and lacking in character.
I sort of get the popularity, though - the "Runza" is fast food, relatively simple in concept, and it's got beef in it, so that's A+ as far as a lot of Nebraskans are concerned. I simply wish we were known for something that was more visually appealing with a more complex texture and taste. Bishop's recommendation of the Reuben would certainly get my vote.
(For the record, I think the Runza hamburger is a damn good fast food burger, perhaps the best fast food burger in Nebraska.)
