We've never had a problem with their food so must've been a freak thing. Ate lunch there yesterday. Had chickenquesadilla, regular challupa, and a taco. My husband had chicken challupas and a chicken crunchwrap. I came down with a pounding headache, cramps, and watery diarrhea within a couple hours that's still going nearly 24 hours later. And my husband got hit with a migraine and upset stomach, then started puking this morning.
