How do I see which shops there are here? Is there some kind of mall directory?

You can view them on Google maps street view if you cannot find the site, I know there is a Meatheads, a wingstop, petco, Mariano's, Ashley home store, tanning salon, sprint, jewel osco & Walgreens not sure if there is more stores

Try Google maps OR Google street view.

Scroll down to site plan. Will provide list of stores. Hope this helps.. https://www.regencycenters.com/property/detail/90034/Roscoe-Square
