111 S. Providence - former Osco space maybe?

Good call. Apparently it was originally a Katz Discount City, then Skaggs Drug, then Osco.
The Parkade Food Barn was a former Walmart (which originally had been a Kuhn's Big K). Walmart moved to a former Woolco at Biscayne Mall, which was a rare store of theirs with a mall entrance. The Biscayne Kroger was a late non-Superstore that looked older than 1972. The 2101 W Broadway Safeway closed in 1984.
