Beauty Bar Brooklyn - NYTimes.com David B. Torch for The New York Times Erina Dempsey, a manicurist, paints nails next to a Paul Mitchell Swizzle. WHEN Beauty Bar, the kitschy salon-themed chain, first ventured into Brooklyn in 2009, it landed on a gnarly patch of Bushwick. Gentrification didn't catch up, and it closed. Since then, outposts have opened in places like Chicago and Denver. Last month, like a young adult trading loft parties for PTA meetings, it returned to Brooklyn, this time to staid Park Slope. On a recent Saturday, the scent of nail polish lingered as a chatty crowd sipped cocktails and pints of beer. "You could sell $2 PBR's all night, but it was nothing," said Paul Devitt, the owner, explaining the drawbacks of Bushwick. He pointed out a machine that, instead, serves wine on tap. "This is a little more mainstream," he said. THE PLACE Beauty Bar occupies part of a former coffee shop on a stretch of Fifth Avenue notched with bistros and delis. Walls are covered with glittery geometric patterns, and a central bar can be advanced upon from all sides. There is retro furniture, naturally: a plastic-covered couch rescued from Habitat for Humanity shares space with hair-drying chairs. THE CROWD Even before Southpaw closed in February, Park Slope boasted more boutiques selling microbatch dog sweaters than night life destinations. These patrons are not bound for Lavo: bespectacled men wearing collared shirts beneath cardigans, women with close-cropped hair, a few optimistic scenesters and older couples on date nights. Around 1:30 a.m., the assemblage thinned. "This little neighborhood empties out early," Mr. Devitt said. Late night is tough. GETTING IN No cover charge or dress code. For combatants in the endless baby-in-bars skirmishes, children should be out by 7 p.m. PLAYLIST A bubbly mix from artists like the Neptunes and Panjabi MC pumps from an iPod. DRINKS As expected in a neighborhood of community-supported agriculture, draft beers include local products like Brooklyn Blast IPA ($8) and Kelso Pilsner ($6). From 6 to 10 p.m., a manicure with a martini is $10. Cocktails like the Paul Mitchell Swizzle (lime, pomegranate grenadine, mint, vodka) are $10, too. Beauty Bar, 249 Fifth Avenue (between Garfield Street and Carroll Street), Park Slope, (718) 788-8867; thebeautybar.com. Open Monday to Thursday 5 p.m. to 4 a.m., Friday and Saturday from 3 p.m.
