Koster and Bial's Music Hall was an important vaudeville theatre in New York City, located at Broadway and Thirty-Fourth Street, where Macy's flagship store now stands.

The music hall featured many top performers of its day and is famous in cinema history as the site of the first public exhibition of the Vitascope on April 23, 1896.

At that location, Koster and Bial had taken over Bryant's Opera House, a venue for minstrel shows.

They offered food and drink along with vaudeville, circumventing a law against serving alcohol in theatres by replacing the curtain with a folding fan.

[citation needed] Quickly running into financial problems, Hammerstein decided to convert his theatre to a vaudeville format.
