The Geoffrey Off Broadway in downtown San Diego's Gaslamp Quarter occupies a 100-seat black box on the First Avenue side of the historic 1912 Spreckels Theatre Building, named in memory of Geoffrey Shlaes. Converted from a former USO space in 2014 with assistance from the San Diego International Fringe Festival, the room serves as the Fringe Hub's home base — a smaller-format counterpart to the 3,000-seat main stage at San Diego Civic Theatre. Programming rotates between independent theater, cabaret, contemporary dance, and live music, with the local late-night talk show Tonight in San Diego having filmed three seasons on the stage. The flexible flat-floor layout accommodates thrust, traverse, and in-the-round configurations, an adaptability shared with multipurpose performance spaces like Copley Auditorium in Balboa Park. Multi-show festival runs — with consecutive companies loading in and out of the same 100-seat footprint across a single weekend — are the Geoffrey's most logistically demanding bookings.
