Can you guess the year this photograph was taken, and guess where exactly these gents were hanging out? As always, we'll update later with the answer and more details.

UPDATE: This photo, courtesy of the Museum of the City of New York, was taken in 1900 at the Casino Cafe in Central Park. The caption reads: "Bar, bartenders, customer and photographs on the walls with ornate architectural detail."

The Central Park Casino's original building was designed by Calvert Vaux and "intended to be a place for refreshments [a Ladies Refreshment Pavilion]. In the 1920s, it became a prime nightclub for wealthy socialites." As with many things in New York, eventually Robert Moses demolished it, claiming the Casino "catered to a wealthy clientele (with menu prices greater than the bill of fare at the Plaza Hotel), and thus was an inappropriate use of a public park. He also claimed financial mismanagement by concessionaire Sid Solomon and the Dieppe Corporation." It was replaced with "a playground laid out on a concrete pad," and today is the site of Rumsey Playfield/the Summerstage concert series.
