Banzai Institute

From Memory Alpha, the free Star Trek reference.

The Banzai Institute was an organization that had a location on Deep Space 9's Promenade, at address 01-088. (Star Trek: Deep Space Nine)

This was listed on a directory graphic on the Promenade created by the art department, and contains a number of in-joke references to other media, such as this reference to the film The Adventures of Buckaroo Banzai Across the Eighth Dimension!.
