Ben's Chili Bowl Restaurant, a famous diner in Washington for politicians and celebrities, has lost its founder Ben Ali who died Wednesday of natural causes, the restaurant said on its website.

Ben's Chili Bowl diner is a landmark place for the black business community in Washington. It opened in 1958 and is famous for its bowls of chili and its chili-covered half-smokes.

President Barack Obama visited for lunch in January. Bill Cosby visited too and famous jazz musicians Duke Ellington, Ella Fitzgerald and Nat King Cole were known to visit the diner.

Ali founded the restaurant with his wife Virginia in an old movie house.
