There's a serious club scene happening underneath the downtown Iron Cactus, for those of you who didn't know. Follow the winding staircase into a outdoor bar scene, where smokers (lots of them) congregate and wait for friends to arrive. Head inside to the blue glowing lounge for blasting electronic music, like house and dub-step, and for drinks served up by fast-moving bartenders. Unlike in other "clubs" where dancers line the walls, people here really get on the dance floor that surrounds that resident DJ stage.
