Located at 609 Fourth Avenue at the southwestern reaches of Park Slope, Supercollider is part cafe/part bar (okay, mostly bar).  Offering 16 quality, mostly US domestic draft beers, Supercollider is a great beer lovers spot on a rather drab stretch of Fourth Avenue. Front half of the space is the bar; back half has a few tables and two pinball machines. A few board games also available. Supercollider is a solid spot for any Park Slope craft beer bar crawl.
