Sbarro filed for Chapter 11 reorganization on Monday for the second time in three years.
The struggling pizza chain shuttered 155 of its American locations last month, citing declining traffic in the mall food courts where it does much of its business. It said it still has more than 800 locations worldwide.
The company, which is based in Melville, N.Y., did not provide details on whether any marketing or in-store changes were planned to help update its image and improve sales.
Sbarro filed for bankruptcy protection in April 2011 and emerged a few months later, saying that it significantly cut its debt and received a capital infusion.
