A kitchen fire forced workers to evacuate a restaurant at the Prime Outlets near Grove City.

Fire crews were called to the Primanti brothers in Springfield Township just after 1 a.m. Tuesday

Investigators say a cleaning crew discovered a small fire behind the stove and had called for help.

The workers were the only ones in the restaurant at the time and no one was hurt.

The restaurant did not open at 11 a.m. as usual.  An employee told 21 News they hope to reopen by 3 p.m. Tuesday.
