That's going to be a very long shot. Most of their stores built in the 50's and 60's looked exactly like that and there is nothing in the background or forground that would distinguish it. It looks very much like the store at 3rd & Fairfax in Los Angeles (now a Ross).
Unless the stores were so much the same I think this was in Anaheim at Ball Rd. and State College which much of the building is intact and I believe is an independent Fiesta Mexicana or Fiesta Foods.
