The coronavirus pandemic was the final blow for many restaurant chains, which were already struggling with growth in third-party delivery and consumers’ migration away from shopping malls. On Sunday, Friendly’s — an 85-year-old East Coast chain known for its ice cream — was the latest to file for Chapter 11 bankruptcy protection.

Here are some of the biggest chains to seek bankruptcy protection this year:

Orlando, Florida-based Earl Enterprises, the parent company of Planet Hollywood and Buca di Beppo, has reopened 49 locations and plans to reopen seven more in the coming weeks.
