While named for the World War I-era bunkers at Rockaway's Fort Tilden, Battery Harris is a Williamsburg bar through and through. With an interior reminiscent of spring break in Baja, the beachy indoor/outdoor bar is flanked with panels of sandalwood, the patio space is sectioned off into palm tree-shaded cabanas, and the walls are plastered with various waterfront magazine cutouts. Maintaining its vacation shtick, the trendy joint offers a Caribbean-inspired food menu, where things like spicy fish tacos and jerk chicken sandwiches are served as late as 4am on the weekends. And perhaps more importantly, the all-day drink menu features an eclectic roster of beers on tap, and a glorious list of paper-umbrella-garnished tropical cocktails, like frozen Thai Piña-Coladas. On Saturday nights, while a macbook-toting DJ entertains on the patio, throngs of vintage-Levi clad Brooklynites wait in avenue-length lines to gain entry to the casual, scenic nightspot.
