For those who want to see pop stars or just dance the night away to their greatest hits, these two adjoining clubs, The Factory and Ultra Suede, are just the place. The giant space is Boystown’s pop music playpen; on Friday nights, the speakers thump everything Britney, Christina, and Madonna. Once in a while, real live lifestyle icons like Jessica Simpson and Debbie, ahem, Deborah Gibson appear for a performance. Every third Saturday of the month, the two clubs connect to form one big party, with three different rooms dedicated to ’70s, ’80s and ’90s dance hits. The crowd is mainly gay, but the club is open to anyone and everyone who loves to get down.
