The shops inside the mall were usually of the same type no matter where in the US the mall was located.
There was a large chain department store, sometimes called an "anchor" store ( it anchors all the other shops), and there were usually discount clothing shops such as the GAP or Old Navy.
There was at least one chain book storte. There were pet shops, drug stores, gift shops (Hallmark was a common shop).
There were also toy shops, such as Toys'Rus and game centers, and even movie cinemas in the larger malls.
It was popular for teenagers to go to their local mall after school (no juke in America) and "hang out".
"Hanging out" consisted of walking around the mall upstairs and down, or sittin in the food court and "people watching" especially the opposite sex. This was before mobile phones, so kids were not distracted by that technology.
Nowadays, online shopping has really hurt the shopping malls, although some are trying to survive by offering specialty shops or hgigh-class decoration. But the kids have mostly moved on... (G.K)
