Panchero's has returned to Ames. It's down by Best Buy on South Duff, but it's a had a considerable makeover from what we remember in college. It's "gourmet" burritos now with black beans and rice. No 2-pounder, and no chorizo.
It is NOTHING like what it used to be. Just last weekend I got food poisoning at the one on 100th street in Urbandale. Won't be going back.
