The staff used hand-written tickets to process sales before the lights came on there and at most other stores about 45 minutes later.
However, Bloomingdale's - one of the mall's anchors - remained in the dark as of 2 p.m., and it was not known when or if power would be restored there. Employees standing at the store's entrances handed out $15 mall gift cards.
The cause of the outage remained unclear Friday afternoon.
