A lawyer in Miami-Dade is suing some clubs for gender discrimination -- he believes ladies' nights, where women drink for free, exclude men. He'd have a field day in Broward County, where not only can women imbibe on the house in certain establishments, they can also dine without spending a dime. In addition to Joseph's Landing and Hot Chocolates, Truffles (2861 E. Commercial Blvd., Fort Lauderdale, 9547718336), the upscale, masculinely decorated steak house that replaced Smoke, now allows females to sup sans the check on Monday nights. The catch, of course, is that men can't be along -- the ladies must dine without an escort. Discrimination? Or the solution to dating dilemmas? Ladies be the judge.
