Donna - NYTimes.com WHILE the north side of Williamsburg, Brooklyn, has become a shadow meatpacking district, its south side has matured into its own night-life destination, with an inscrutable mélange of condo-stacked yuppies, art kids and entrenched Latinos. Case in point is Donna, a handsomely elegant bar that opened last spring just south of the Williamsburg Bridge. During happy hour on a crisp Friday night, jabbering 30-somethings could be found unwinding at the bar. In vintage Williamsburg fashion, a sweater-clad trio debated hosting a potluck dinner. But then the conversation shifted, indicative of the neighborhood's new professionals.

On one Saturday night, the D.J."s selection of giddy funk and world music was a sonic wormhole to Fort Greene's neo-soul era of the early Naughts. There are sporadic live performances from bands of a similar pastiche. Bring your own Nag Champa, maybe. Reading the uber-twee handwritten cocktail menu is like deciphering a Maya calendar, but drinks have better composition. The Smokey Peach ($10) with tequila, mezcal, lime and the namesake stone fruit has the ideal Oaxacan warmth for fall evenings. Local beers like Sixpoint Sweet Action ($7) are served alongside cheaper offerings like Narragansett ($4), which is a marketing campaign away from being the adult version of Pabst Blue Ribbon.
