Every new nightspot in Scottsdale gets long lines out the door — for the first couple of months, at any rate. The real test is whether people are still willing to come out and line up long after most everyone's gotten a look at what's inside. In the case of Cake, which opened in January, its staff is still dealing with big crowds and no signs of slowing down, so we'd have to dub it a success. What's the draw? The staff of comely, lingerie-wearing CakeDolls might have something to do with it, as might the aerialists and burlesque performers who strut their stuff amid the club's stylish chateau-meets-bordello décor. When most of its neighbors surrounding Saddlebag Trail club zone are geared toward flat-out partying, Cake offers panache in addition to a staff of highly selective doormen who allow young and hot females to cut to the head of the line. Cake, in essence, takes the cake.
