Fatburger's parent company is in trouble

FAT Brands has filed for Chapter 11 bankruptcy protection.

Restaurant franchiser FAT Brands, which owns popular fast-casual chains including Fatburger, Johnny Rockets and Twin Peaks, has filed for bankruptcy amid a mounting debt of roughly $1.3 billion.

The California-based company, which oversees 18 restaurant brands with more than 2,200 locations worldwide, filed for Chapter 11 bankruptcy in Texas on Monday. …

The franchiser emphasized that its signature brands such as Fatburger, Johnny Rockets and Round Table Pizza are expected to remain operating as usual during the Chapter 11 process.

Rather a lot of scandal felonious fraudery in their history: FAT Brands - Wikipedia.

I only know of this place from a single Beastie Boys lyric:

I chill at White Castle
'Cause it’s the best
But I’m fly at FatBurger
When I’m way out west.
