The premiere hunting grounds for angular debutantes and the Wall Street players who love them, Whiskey Blue, at the W Hotel, has cropped up in bright cities across the country shilling its special blend of high-life sophistication and lounge-y hedonism. Plush leather divans invite patrons to engage in something a little more than sitting, while white-sleeved bartenders mix martinis and Cosmos from behind a mahogany and alabaster bar. While Whiskey Blue struggles as a viable nightlife locale, it excels as a happy hour hangout for the upwardly mobile.
