The Fatburger menu is centered primarily on hamburgers, offering various sizes and numbers of patties, along with add-ons such as cheese, bacon and eggs.

[2][3][4] Fatburger was founded by Lovie Yancey (1912–2008) in the neighborhood of Exposition Park in Los Angeles, California, in 1947.

On August 15, 2003, Fog Cutter Capital Group completed a $7 million investment and financing package for the company.

[6] For several months in 2006, the company was barred from selling additional franchises in California, due to chairperson Wiederhorn's felony convictions.

[7] In 1992, Fatburger gained national attention after being referenced in the hit song "It Was a Good Day" by rapper and actor Ice Cube.

[11] Owing to the success of the burgers and positive response in Pakistan, Fatburger opened its biggest flagship outlet globally in June 2013 in Lahore.

[12] In July 2015, a branch in Lahore was shut down by authorities due to health and food safety reasons.
