Crews were dispatched at about 2:50 a.m. to the restaurant at 819 State St. for reports of fire alarms ringing, Capt. George Martinez told Noozhawk.
First-arriving crews found the restaurant filled with smoke and fire sprinklers going off, Martinez said, and additional firefighters were dispatched.
Firefighters pulled a hose to the front door of the structure and forced entry into the business, where crews discovered a small fire in the kitchen, Martinez said.
The fire sprinklers were able to douse most of the flames, Martinez said, adding that they prevent fire damage to most of the business.
No injuries were reported.
Three engine companies, a truck company, and a battalion chief were deployed to the scene.
The fire was determined to be accidental in nature, according to fire Engineer Kevin Corbett.
The restaurant will be closed until repairs can be made, Corbett said.
