A fire swept through a restaurant on Ogden Avenue in Brookfield on Aug. 25, causing significant damage to the building and shuttering the business indefinitely.

According to Fire Chief Patrick Lenzi, the blaze appears to have started in a rear addition to the building that housed Dunav Restaurant, a Serbian eatery at 8801 Ogden Ave. The kitchen is located in that portion of the building.

Lenzi said the cause of the fire is still under investigation, but it appears to have started shortly after the restaurant closed for the night. The restaurant’s owner said the last person left the business about 10:45 p.m.

Just before 11 p.m., a Lyons resident who was passing by the building noticed smoke coming from the building and called 911.

When firefighters arrived, said Lenzi, they reported observing fire in the rear of the building, with the rear wall engulfed in flames.

The building was somewhat unusual, said Lenzi, because the roof of the main building and the addition overlapped, creating open areas between the two roofs. Firefighters continued to encounter pockets of smoke around the roof area “from front to back,” said Lenzi.

“We didn’t leave until all the hot spots were gone,” he said.

In the process of finding all those hot spots, firefighters took down a good part of the ceiling in the seating area of the restaurant in the front of the building. Ceiling fans and light fixtures dangled from the ruined ceiling in the aftermath of the fire.

Firefighters from eight other suburban departments, including Riverside, LaGrange, LaGrange Park, Lyons, McCook, Summit, Forest View and Western Springs assisted at the scene, which wasn’t cleared until about 4:30 a.m.

It’s the second fire at an Ogden Avenue restaurant in the past month. In late July, a gas meter fire damaged the rear area of La Cabanita Restaurant.

Dunav restaurant is the fourth restaurant to occupy 8801 Ogden Ave. since 2008. Mick Gajic and Lou Bojic opened the restaurant in August 2011, naming their business after the Dunav River (that’s Danube in Serbian), which runs through Gajic’s hometown of Smederevo, Serbia.
