Step 1 : Introduction to the question "Which famous theater is located in New York City's Harlem neighborhood?"
The Apollo Theater is a music hall located at 253 West 125th Street in the Harlem neighborhood of Manhattan, New York City. It is a noted venue for African-American performers, and is the home of Showtime at the Apollo, a nationally syndicated television variety show which showcased new talent, from 1987 to 2008. The theater, which has a capacity of 1,506, opened in 1914 as Hurtig & Seamon's New Burlesque Theater. It became the Apollo in 1934, when it was opened to black patrons – previously it had been a whites-only venue. The building was designated as a National Historic Landmark in 1983.
