103 Harriet is a venue found in San Francisco's Soma district, open since 1986 and home to some of the city's premiere house and techno events over the course of its lifetime. The club itself offers 20,000 square feet of space, holding up to 1,200 clubbers spread over five rooms, each equipped with its own DJ booth. There's an emphasis on style and appearance, with hardwood floors and silver tiles, plus visual amenities like a 400 square foot "water wall" (also used as a projection wall) as well as a colour-customizable room.
