The commercial equivalent of a bedroom community. Just as a bedroom community would be a suburb or area with mostly apartments and houses and little to no commercial activity, a shopping town would be a suburb or area with mostly indoor malls, restaurants, and strip malls without any housing in sight.
"My parents took me to the nearest shopping town to buy a new cell phone for my Dad, and my Mom and I browsed through the other stores while we were there."
A mall that was once the place to be, but now exclusively crazy people hang out there.
"The only restaurant at shopping town mall is that creepy China express."
"Why go to shopping town when you could do literally anything else."
