Park Slope is the center of Brooklyn's albeit limited gay nightlife scene, and one of the better little queer bars in the neighborhood is Excelsior (390 5th Ave., 718-832-1599), a small and generally low-keyed locals' hangout drawing a mix of Outer Borough hipsters, longtime nesting Slope-ians, and the occasional tourist out for a gay Brooklyn booze cruise. The bar is along busy 5th Avenue, near a number of other gay-popular cafes, restaurants, and cocktail bars. Another fun LGBT bar just down the street is Ginger's, which is somewhat more popular with the lesbian set but also mixed-gender. N.B. - when the weather's nice, sip your cocktail on Excelsior's small back deck.
