Actor-turned-restaurateur Harry Lewis has died at the age of 93.

He passed away from natural causes on Sunday (09Jun13) at a convalescent home in Beverly Hills, Los Angeles, according to his publicist Greg Rogers.

Born in Hollywood in 1920, Lewis entered the U.S. Air Force at 19 before signing a contract with Warner Bros. after World War Ii.

He starred in the Humphrey Bogart 1948 classic Key Largo and secured small roles in several movies including The Unsuspected, The Harder They Fall and the 1981 miniseries East of Eden.

In partnership with his wife Marilyn, he went on to launch the showbiz-hotspot restaurant chain Hamburger Hamlet, the first of which opened in 1950, before selling the chain in 1987 for $33 million (£21.29 million).

The couple also set up the popular eatery Kate Mantilini on Wilshire Boulevard, where Al Pacino and Robert De Niro filmed a scene for their 1995 movie Heat.

The couple added a second Kate Mantilini in Woodland Hills in 2003 and Lewis worked in the restaurants daily, only retiring from his duties three years ago.
