Celeb-studded late-night dining destination STK is about to make starlets (and the paparazzi who love them) even happier, with the launch of Coco De Ville (pictured). The lounge, adjacent to STK, is scheduled to open next weekend. The bar couldn’t be more different than STK, with hot pink, green, black and purple all competing for your attention. Two multicolored swings-with-cushions hang from the ceiling at the bar, which has a separate entrance, a DJ area and a smoking patio. . . . Cahuenga’s Goa has expanded its hours after being open only Thursdays and Saturdays. The Indian-themed club, host to Kanye West’s after-party Tuesday and slotted for a cameo in MTV’s “The Hills” this season, is featuring house music on Wednesdays. . . . Spaceland honcho Mitchell Frank and first-time bar owner Jeff Ellermeyer have opened an upscale beer bar, El Prado (1805 Sunset Blvd.). The cozy spot across the street from the Echo, technically in soft launch mode, features exposed-brick walls and a long, wooden bar.
