If you're talking about Dawn of the Dead, don't bother. Its literally just a mall and it sucks now compared to back in the day.

FUN FACT: Dawn of the Dead was set in Philadelphia, but filmed in Pittsburgh.

"Dawn of the Dead

Monroeville Mall is most famous as the filming location for the 1978 movie Dawn of the Dead, directed by George A. Romero. In 1977, George A. Romero began filming Dawn of the Dead on location at the Monroeville Mall. All filming inside the mall took place at night after the mall had closed, with filming often continuing until dawn. Filming inside the mall began in October 1977, but had to be suspended when Christmas decorations were hung shortly after Thanksgiving. Filming resumed in January after the decorations were removed. It was during that break that much of the mall's exterior shots were filmed, as well as filming at other locations. In the film's storyline, the mall was used as a fortress to protect four human survivors from a world taken over by the walking dead. Several pictures taken during the filming are on display in a room on the upper level near Macy's. In addition, Monroeville Zombies, located on the lower level near Macy's, featured an in-store museum and gift shop dedicated to celebrating zombies in film and pop culture. The museum's main focus was Dawn of the Dead and contained artifacts, memorabilia, scale models of the mall as depicted in the movie and a boiler room walk through with various life-sized replicas of movie zombies.[9] In 2013, the museum was relocated to Evans City, PA, home of the original film Night of the Living Dead. In October of 2020 the Living Dead Museum relocated back to the Monroeville Mall and is located on the upper level."
