The patio behind this rum bar in Prospect Lefferts Gardens is likely too massive to qualify as secret (it’s also in the name of the bar), but it’s possible you don’t know about this place since it only opened during the summer of 2020. There’s a huge fenced-in area with lawn chairs, turf, and murals galore, and tons of special programming beyond the cocktails and snacks on the menu. Check out their Instagram page so you don’t miss one of their special pop-up nights or live music events.
