Two longtime downtown chain restaurants have closed.

The last day of business at Gold Star Chili and Great Steak & Potato was Thursday, according to Dad Alexander, an employee of the Dayton Mall Gold Star location.

Like the two franchises that had operated at 137 N. Main St., the Dayton Mall Gold Star is owned by Jamil Shteiwi.

Shteiwi did not immediately return messages seeking comment.

It was not immediately clear why the business closed.

Kristen Wicker, a spokeswoman with the Downtown Dayton Partnership, said a location is being sought that could better meet Shteiwi’s needs.

Great Steak & Potato serves cheesesteak sandwiches in hundreds of locations throughout the United States, Canada and abroad.
