UncleVic, Nashville hot chicken should still top your list, no competition! As for that flaky tortilla, most good ones do that, and that's par for the course in NM (well, should
be). I'd figure those black olive-looking bits are charred morsels from the brisket's skin -- and I doubt there's anything like this outside of NM. Amy & I spent two weeks roadtripping there last summer, and it was one of the most wonderful RF trips we've ever taken!
