The fire started in the kitchen and serving area. The cause of the fire was accidental, Fire Chief Anthony Armstrong said.
An unused warming pan was found to be accidentally turned on, Armstrong said.
The damage was estimated at $100,000. The interior received heavy smoke and water damage, but the building sustained no structural damage, Armstrong said.
The fire department responded to the fire with two pumper trucks and 17 firefighters.
Sallisaw Police Officer Travis Buchanan saw smoke coming from the building and reported the fire, Larry Randolph, owner, said.
Randolph reported that the smoke alarm in the restaurant did not go off. Randolph said he had insurance and will rebuild.
