The rush to open bars on 4th Avenue hasn’t quite kept up with the rush to build condos (what could?), but a new nightclub will soon open on the thoroughfare, joining the cluster between St. Marks and Bergen, and farther south, Cattyshack. Garfield’s (on Garfield Street and the west side of the avenue) is set open within the next month or two. We don’t have a ton of details about the business, which is going to be a nightclub, but the under-renovation space has looked extremely large whenever we’ve peeked in. GMAP
