KNOCK, KNOCK, KNOCKIN' ON HEAVEN'S DOOR: There are few clubs in Atlanta that feel like a hidden secret. Although Halo is known and frequented by many people, you'd never know it was there unless you spotted the steady stream of people making their way down a side street toward the nondescript door. Upon entering, the lounge/bar/dance club has something to suit almost any mood. The large "minimalist and de-constructivist" space is broken up into a lounge area with couches and small tables, a mezzanine dance area where you can move to the guaranteed-to-induce-a-rave-flashback beats, and an area surrounding the backlit, white onyx bar that changes colors throughout the night.

SAINTLY SIPS: The glowing bar staffed with good-natured bartenders is the most popular area of the multi-tiered lounge, and for good reason. Forget the basic beer selection and go for the cocktails, which are made with "call or better" liquors and are skillfully mixed.

THE INNER CIRCLE: Let's be honest: A lot of nightlife hangouts, whether you're in Virginia-Highland, Castleberry Hill or Buford Highway, still seem monochromatic. But Halo is a place everyone will feel comfortable, and its diverse crowd is the best reason to visit.

Halo Lounge, Mon.-Fri., 4 p.m.-3 a.m.; Sat., 6 p.m.-3 a.m. 817 W. Peachtree St. 404-962-7333. www.halolounge.com.
