Fire fighters crawled through the restaurant and extinguished small fires and burning embers throughout the interior…They spent hours on scene dealing with hot spots in the above-ceiling crawl space and attic of the 
one-story building…the building didn’t have a sprinkler system and damage is estimated at more than $450,000.
A fire in a Des Moines restaurant likely burned for more than an hour before being detected and it took firefighters several more hours to completely extinguish all the hot spots, officials said. Crews responded to Montana Mike’s, 5030 NE 14th St., around 5:10 a.m. Tuesday to find dark gray smoke from floor to ceiling, fire officials said.
Heavy smoke and heat made seeing initially impossible and limited the use of a thermal imaging camera, officials said.
The fire started in the back of the restaurant, near office equipment, storage and laundry machines, authorities said. The cause is still under investigation.
