For a hip, late-night hangout spot, look no further than the Bikini Lounge in central Phoenix. This is one of the oldest bars in town, as well as one of the most retro-inspired. The tiki-themed bar attracts a younger crowd, as well as older Phoenix natives with a soft spot for the bar's retro digs. The bar is small and gets crowded easily, but the service is consistently quick and speedy. Great drink specials, live music, DJs and a small dance floor add to the merriment. Note: this is not the place to go for an upscale dance club experience, but it's an unpretentious place to let loose with friends.
