It happened at 2 a.m. Saturday at the Domino's in the 1200 block of Delaware Street.
Police say the gunmen forced their way into the store and demanded money from a worker at the counter.
They then forced that worker and two others into a freezer, locked the door and fled with an undisclosed amount of cash.
One worker was treated by medics at the scene.
There have been no arrests.
