The Neptune Diner, a beloved Astoria landmark for 40 years, closed its doors on Sunday due to an inability to renew its lease, which expired in 2019. Longtime patrons expressed deep sadness over the diner’s closure, recalling cherished memories and family traditions tied to the establishment. The property will be redeveloped into residential units following a City Council-approved rezoning plan. The diner, known for its 24-hour service and community atmosphere, had been a staple in the neighborhood, with many customers lamenting the decline of similar establishments in New York City. As diners continue to disappear across the boroughs, the loss of Neptune underscores a significant cultural shift. Local residents highlighted the diner’s role in their lives, marking the end of an era in Astoria.
