While the cause of the early morning fire at Casablanca Steak House, 140 S. 25th St., remains under investigation, Fort Dodge Fire Chief Steve Hergenreter said there’s no evidence to suggest it was suspicious.

“At this stage, there’s no evidence to think this fire was suspicious,” Hergenreter said.

The fire, which left the restaurant with extensive damage to the kitchen and bar area, was reported at about 4:30 a.m. Thursday.

No one was injured.

Twenty-four firefighters and paramedics responded.

Crews were on scene until 8:30 a.m.

The fire, which burned a hole in the roof, was contained to the rear portion of the building where the kitchen is located.

Investigators with the State Fire Marshal division are assisting in determining the cause.

Hergenreter said it could be weeks before an exact cause is determined.

The restaurant is owned by Alfonso Galvan, who also owns Lomitas Mexican Restaurant, 2223 Fifth Ave. S.

The Casablanca Steak House opened in September of 2018.
