Most Mondays are a useless blur of team meetings and breakout meetings, with the occasional impromptu meeting to break up the monotony. No one gets any work done. So why not sit there with a churning stomach, a pounding head and the nauseating stench of stale smoke? Besides, you have other things to worry about, such as the name of the person you left asleep back at your apartment or the location of your car. "Naked Sunday" at Nikita forces the dying hours of the weekend to cling for a few more breaths. At 10 p.m. they dim the lights and crank the volume. Crowds pour in, vodka sloshes, soft-core porn appears on two flat-screen monitors and, for a moment, Saturday night returns. Patrons know that Monday lurks at 2 a.m., so they beat it back with the only weapon they have: massive doses of alcohol. Do Naked Sunday right and you won't think about the workweek until after you figure out where you are when the alarm rings Monday morning.
