The small fire was found in the second floor kitchen at White Star Ale House, but officials said it was being held in check by the sprinkler system. No one was at the restaurant when the fire occurred.
In a release, officials said a bag of rags ignited due to animal fat from the grease and heat from being laundered earlier in the night by staff.
Officials said the building suffered minor damage.
Firefighters encouraged residents and businesses to spread out laundered clothing or towels after removing from the dryer to allow them to cool.
