Dance Clubs: One of the trendiest nightclubs in Atlanta, Lava Lounge or CosmoLava, combines two clubs in one: Cosmopolitan bar and Lava Lounge. The two are connected by an outdoor deck. Cosmo is more upscale with dark wood and swanky sofas. Lava has a lava-surfaced bar and a cozy lounge area. The dance floor, located on the lower level, streams the latest house and industrial beats. Other rooms play a wide range of musical genres like '80s or hip-hop. Club-goers lean young and linger by the bar to sip on house cocktails while taking a break from dancing. Service at the bar is quick and bartenders are friendly.
