A fire left heavy damage inside The Cast Iron Kitchen, a new restaurant at 5441 Jones Creek Road, and sent one firefighter to the hospital with minor injuries Sunday evening, said St. George Fire Department spokesman Eldon Ledoux.

The fire started just before 6:30 p.m. towards the back of the restaurant and was contained in that unit of a strip of stores because of a fire wall, Ledoux said. The restaurant was not open at the time and no one was inside, he said.

The firefighter was injured when part of the ceiling collapsed, Ledoux said. The fire was under control by 7:30 p.m.

Owner of The Cast Iron Kitchen, Jonathan Marino, was concerned about the damage. The restaurant had only been open seven months, Marino said. A 'Now Open' sign still hung at the entrance.

"It's going to be a pretty big loss," Marino said.

The unit next to the restaurant, an embroidery and monogram shop, also sustained heavy smoke damage, Ledoux said. 

"The smoke was really bad," said Sherry O'Neal, that shop owner. She came out to the scene when she heard about the fire and was waiting to see how bad her store was affected.

"I don't know what's going to happen now," O'Neal said. 

Fire investigators have not yet determined a cause, but Marino said preliminary indications are it was an electrical issue.
