Square Diner is a tiny diner on Leonard Street at Finn Square in Tribeca, in a railroad-car-style building made by the Kullman company and placed here in the 1940s.
Eater New York calls it a reminder of Tribeca’s manufacturing past and a relaxing hang. Reviewers praise the soft pancakes, free coffee refills and fair prices. Favorites include homemade corned beef hash with eggs and the lumberjack breakfast.
