The Grand Theatre is a location in our upcoming indie game/visual novel, "Sam in New York," which is set in 1920s New York City.
The Grand Theatre is a Yiddish Theatre, although there are some Italian performances from time to time. In short, it is a theatre mostly used by Jewish and Italian immigrants (and their children) in the Lower East Side.
The protagonist-player, Sam, often frequents this theatre, as he is interested in acting.
