Where is Tom's restaurant, famous from the show "Seinfeld," located?

Tom's Restaurant, which gained fame as the exterior setting for the fictional diner in the television series "Seinfeld," is located at W. 112th and Broadway, one block west of St. John the Divine. This location was chosen for its distinctive architecture and its association with Columbia University, adding to the character of the show. The restaurant's diner vibe, combined with its proximity to the university, contributed to its selection as a backdrop for many of the series' iconic scenes. This makes it a significant landmark not only for "Seinfeld" fans but also for visitors wanting to experience a part of New York television history.

Other locations mentioned do not have the same cultural significance linked to the show. Each of those places may feature notable attractions or landmarks, but they are not associated with Tom's Restaurant or "Seinfeld," which is what the question specifically targets.
