This is one of the few places in town that's so naughtily diverse. There's always a decent array of fauna, but between the hours of midnight and 5 a.m. it runs the gamut from strippers unwinding after a shift and pimps with hookers in tow to hot cops, students in the midst of finals, megageeks glued to their computers, Harley dudes on a road trip and punks rocking Mohawks and ominous tattoos. A bit like the bar in Star Wars, all of these wildly different animals seem to co-exist in relative harmony except for the occasional explosive conflict. But if things do get dicey late-night, by 6 a.m. calm returns when the M-Street exercise crowd arrives in search of some java and post-workout breakfast.
