Rejoice WKNDers! Gaypril is here, and with it, a bevy of lgBT Co-op-sponsored events from a queer hike up East Rock to a lesbian erotica reading. So in the spirit of Pride Month 2011, WEEKEND decided to investigate some of our favorite gay bars (and bars with “gay nights”) — places to visit after the pride picnic ends. We bring you Partners, York Street Cafe, gotham and Center Street lounge.
