PGK Art: Filthy McNasty’s on Essex Street, between Houston & Stanton Streets. Here’s the skinny: two-for-one happy hour (5 to 8 p.m.), pool table, dart board, trashy tap beer (PBR, $3; Yuengling, $4), copious buybacks, graffiti galore, “wall of shame” (pix featuring drunk sorority girls dancing on the bar, Moby and some chick, the bartender and some stripper, etc.), $2 nachos with warm squeeze cheese (“You’re brave souls,” says the bartender. “I’ll get some chips from the basement!”), Photo Hunt video game (an X-rated “which one is not like the other?”; Maldoro: “Never underestimate the power of naked women!”), and a $5 Friday-night kill-the-keg marathon.
