Mobster Benjamin "Bugsy" Siegel sat down to dinner at Jack's at the Beach in Santa Monica on the night of June 20, 1947 and ordered trout, which turned out to be his last meal.
The LA Times, and other sources, including a biography of Siegel, mention the type of fish he ate, while a blog called "Dining with the Don" alleges that Siegel had grilled trout.
Meanwhile, the YouTube channel "The Last Supper" claims it wasn't trout but fried shrimp and French fries that Siegel ate that night, but it doesn't give any backing evidence.
