He went on to open Simon Kitchen & Bar at the Hard Rock Hotel and Casino in Las Vegas in 2002 and later founded several restaurants around the U.S., including Simon Prime in Atlantic City, New Jersey and Simon LA in California.

Simon was also a fixture on TV, appearing on reality shows Iron Chef and Hell's Kitchen.
