Luke Cage rented a 3rd story office/apartment at the Gem Theater for a number of years.
The Gem Theater is located on 42nd Street near Times Square, one of the seedier areas of Manhattan (if not the United States). It was operated by D.W. Griffith on behalf of his Uncle Max. The Gem Theater is noted for showing "B" Westerns. Cage, an admitted Western fan, seems to enjoy the genre. However, he has often complained that the late-night showings disturb his sleep. The often sarcastic Bertha was often on duty as the ticket seller.
Cage's adventures have trashed the Gem several times. His epic battle with the original Power Man in the auditorium led to the Gem being closed for months. The Gem was eventually completely destroyed by explosives from Cage's enemies. 
However, the Gem was rebuilt and somewhat re-designed at its same seedy location on 42nd Street. High on Acid Z from a party D.W. hosted in Luke Cage's apartment, one partygoer jumped off the roof of the Gem. Fortunately, he was caught uninjured by Luke Cage.  When Cage partnered with Daniel Rand, Iron Fist also became a patron of the "Gem". Despite all this turmoil, Cage and Griffith have remained very close friends.
Luke and Jessica Jones moved into the Gem Theater when they switched apartments with D. W. Griffith. They also used it as the base for the Mighty Avengers. While moving in, she spoke to the Blue Marvel (Adam Brashear) about what it's like to raise a child of superheroes and expressed both her support and annoyance at her husband's choice to start another team of Avengers.
- The projectionist at the Gem, Tony, was killed when the Gem was destroyed.

- The Gem Theater held a soda dispensing machine which tormented Luke Cage. For example, it gave him soup when he had selected a soda. Despite D.W. Griffith's tinkering, and an occasional punching from Luke Cage, it was never depicted as functioning properly. The soda machine was a running gag in the Power Man/Luke Cage Vol 1 series.
