DOWNTOWN. A renovated 19th-century building is home to Grasshopper, whose interior mixes aged brick, granite, leather, glass, gilt, antiques, and crystal. The chic venue offers both a dance floor, where patrons groove to hip-hop and R&B, and a lounge, where quieter activities are favored. Curtained-off alcoves provide even more privacy, although they do come at a price. The singles scene at Grasshopper is particularly hot, so be prepared for mingling and lots of introductions.

DOWNTOWN. This sexy hotel bar overlooks the ICON's lobby. A study in red, gold, and black, it provides an appropriately low-key setting for conversation and mingling. Impressive drinks are pricey but tasty, and the smoking cosmopolitan cocktail derives a measure of drama from the inclusion of dry ice. The VIP room is a gorgeous space defined by gilt, lacquer, mirrors, vibrantly patterned fabrics, and a fireplace. Check it out just for the wow appeal. Great for business or socializing.

Amid the sweep of sheer curtains that divide the main space, you're likely to spot a celebrity or two if you watch carefully enough.
