Failing LA restaurant Burger Kitchen appeared on Season 5 of Gordon Ramsay's restaurant rehab show "Kitchen Nightmare." After stealing $250,000 of his son Daniel’s inheritance to open the business, owner Alan Saffron lost countless staff members and thousands of dollars during Burger Kitchen's sixteen months of service.

After Chef Ramsay helped the Saffron family patch things up and revamp Burger Kitchen's menu and decor, Daniel became the acting owner of the restaurant and his parents promised to step down. However, the bad reviews for the burger joint never stopped coming in, and the restaurant closed in 2012 — but that's not the end of it.

During his "Kitchen Nightmares" appearance, Alan Saffron promoted his book "Gentle Satan: My Father, Abe Saffron," which documents his relationship with his estranged father Abe and Abe’s ties to the Australian mafia. The Sydney Morning Herald even reports that Abe Saffron is "Mr. Sin," a notorious criminal figure in Australian history.

Lies, family drama, bad burgers, and alleged mob ties practically doomed Burger Kitchen from the start. Some "Kitchen Nightmares" fan still wonder if Daniel's trust fund money and Alan's own funds had anything to do with the infamous Mr. Sin, but Alan Saffron passed away in 2020, meaning this saga should likely be laid to rest as well.
