Dead people are no doubt bored, so I'm sure these folks would be happy for free food and conversation. Of course, this is just a partial list, subject to addition and deletion. Feel free to add your own in comments.

Buddha, but a light lunch.
Jesus, but kosher of course.
******, come on, who wouldn't.
James Joyce, just to mock him.
George Washington, to try to catch him in a lie.
Hemingway, but just for drinks.
Reagan, to deliver some Depends.
Bakunin, for mutual aid.
William Butler, my ancestor who survived The Wheatfield at Gettysburg.
Audrey Hepburn, but a date, not lunch.
Ingmar Bergman, just to cheer me up.
Ervin Schrödinger, about that cat.
Shakespeare, because I've always wanted to meet an extra-terrestrial.
Ezra Pound, to tell him he was right about usury.
God, to let her know how disappointed I am.
Richard Nixon, so I could drive a stake through his heart.
Julia Child, just to hear her voice again.
Lenin, because he was a self-starter.
Mozart, because he would be fun.
Emma Goldman, to dance.
James Dean, as we look so much alike.
Janis Joplin, because I might get lucky.

Come on, I'm sure you can add to the list. Don't be shy, try.
