Christy's Tasty Queen, in Kansas City, KS, is a reasonable detour off of I-35, and one worth making.
I highly, highly
if you count that last one) recommend a stop there on your journey. I was introduced to Christy's by my BIL a couple of years ago. Since then we have made it a point to stop there on every one of our subsequent KC visits.
Christy's serves a brilliant BPT! Immense in area, but still thick enough to hold in all its juices and remain tender. On my last visit, I tried folding the BPT in half in the bun in order to make it more manageable. Indeed, it mostly
managed to fit inside the bun, but then, getting my mouth open wide enough to accommodate the sudden height of the sandwich became an issue. It was a good problem to have.
There is one potential drawback at Christy's: They have no indoor eating area. If Kansas City were having a milder winter, I'd say sit at one of the picnic tables outside (We did that on our first visit when temps were in the 40s and 50s and there wasn't a flake of snow to be found), but I think you might be overwhelmed by this season's snow and cold. Christy's BPT is so good though, it is worth eating in your car and risking a glob of your preferred condiment hitting your shirt.
BTW, Christy's normal BPT condiment compliment is mayo, lettuce, and pickles. Last time I was there, I asked for them to make one up like a Hamburger; ketchup, mustard, pickle, and onion, and found that to be more to my liking.
Have a great trip!
