Chili in Phoenix?
That would be the Fry Bread House, on 7th Ave just north of Indian School. It hides pretty well; the building itself is set off the road, so look for the sign on the west side of the street. The fry bread is certainly not to be missed, and you can get a bowl of deeeeeelicious red chili and a frybread for (I think) six bucks.
I have not tried it myself but my son told me he had the best chili ever at Wild Horse West which is out by Lake Pleasant,right off the Carefree Hwy and Lake Pleasant Blvd.it used to be right on the road but they have redone the road so you kind of have to look for it,it's on the south east corner back off the road.They also have a good burger.
