I worked there from November 04' to the day they closed, on new year's eve, 2004. The business wasn't doing very well at all; the man who owned it was actually losing money keeping it open. He decided to close the store 2 days before New Years. Our last day, we just gave away a lot of free food and closed the store.
It is not clear on what happened to Jerry's Hamburgers in Provo; however, you can easily contact them through their customer service numbers. This is a business that falls under the Eating place that is normally located in Provo.
