Tom's Restaurant is a diner located at 2880 Broadway (on the corner of West 112th Street) in the Morningside Heights neighborhood of Manhattan in New York City.

[1] It is on the ground floor of Columbia University's Armstrong Hall, home to the Goddard Institute for Space Studies.

Frequented by Columbia students and faculty, it was founded by Tom Glikas in the 1940s and after a sale at some undetermined point has been owned and operated by the Greek-American family of Minas Zoulis, who retained the original name.

[2] Senator John McCain often ate at Tom's when he visited his daughter Meghan when she was a student at Columbia.

[1][2] The interior shown on the television show, however, looked very little like the real Tom's, as indoor scenes were filmed on a set in Los Angeles.
