The chi-chi atmosphere at this CityPlace nightspot simply oozes hip. The toasty faux fire in the fireplace, recessed ceilings set off with red and blue indirect lighting, marble-lit bar tops, and live jazz in the background provide a perfect stage for the martini to cut loose and show off. Mr. Jenkins, the suit-wearing Tanqueray poster boy, would definitely give his nod to the sleek watering hole. Among the more popular of the 20 varieties of imbibable treats at the prime people-watching locale: The Masterpiece Martini with blue cheese-stuffed olives, the Chocolate Martini, a Sex and the City martini, and, of course, the bar's namesake drink.
