It's most famous as the subject of Suzanne Vega's song "Tom's Diner" and as the exterior of the restaurant on "Seinfeld," but the history of New York City's Tom's Restaurant goes back much further than that. The eatery's storied past and continuing importance as a part of pop culture and a neighborhood staple is told in a new film, "Tom's Restaurant: A Documentary About Nothing Everything."

The trailer -- which is a mini documentary itself, clocking in at more than five minutes -- gives a brief synopsis of the restaurant's past and present. It was opened by a Greek family in the 1940s and is still owned by the same clan today.

In addition to serving as the exterior of Jerry, Elaine, Kramer, and George's favorite hangout spot on "Seinfeld" in the '90s (the interior scenes were shot on a soundstage), it also welcomed a slew of famous guests over the years, including regulars like guitarist Bob Rose (who worked on films including "Grease" and "Footloose") and professor and philosopher Dr. Cornel West.

"It's a beautiful place to be," West says of the restaurant in the trailer. "You just see the flow ... of humanity come through Tom's."
