The Upper Crust in Lexington has closed its doors, although it may be temporary.

The Boston Globe reports that several locations of the pizzeria chain have shut down, temporarily at least. 

The Globe called the Upper Crust in Watertown, where an employee who answered the phone said that restaurant was closed and that the company is undergoing reorganization and "we are closed for at least next couple of days."

Upper Crust has been facing financial difficulties, and in September the company defaulted on a TD Bank loan. Company officials filed for bankruptcy protection.

The company's troubles also include a U.S. Department of Labor ruling that they owed employees back overtime pay.
