According to www.chocolate.org, 50 percent of women prefer chocolate to sex. They're sure to find the 24-layer chocolate cake ($14) from the Strip House (1200 McKinney, 713-659-6000) arousing indeed. Yes, there are 24 layers to this potent seducer -- thin, dark layers of extremely moist chocolate cake interspersed with dense chocolate frosting. The whole is topped with an indulgent, hard chocolate coating. The wedge stands five inches tall and four inches wide, and it weighs in at almost a pound. It is sheer decadence -- and at least as satisfying as a tumble in the sack.
