Winnipeg fire crews battled a blaze at an A&W restaurant on Main Street that left the burger chain restaurant completely destroyed on Sunday.

Tony Sawicz was in the area when he noticed smoke billowing out the roof of the restaurant.

He told Global News he dialed 911 just after 5 p.m. when he saw the flames, and in almost minutes he saw crews arrive on scene.

Fire crews were forced to fight the flames from outside of the restaurant, as crews deemed it dangerous due to high heat and heavy smoke.

Sawicz said many people were oblivious to the situation, as vehicles continued to lineup in the drive-thru.

Nearby residents say at least eight firetrucks could be seen working to fight the flames.

All occupants were able to self-evacuate, however, one firefighter suffered minor injuries that did not require hospitalization, said the City.

Crews stayed at the scene of the fire until 2:30 a.m., they added.

The cause of the fire is under investigation.
