The weighty gray of autumn has descended and the state of the world seems more dismal by the day. Time to round up friends and seek refuge in history by jumping around to the best pop music from an exuberantly delusional decade. The crowd at this weekly party is a mishmash of earnest geeks, friendly freaks, and hot young things—and no one can dance, but everyone does anyway. Plus: The club serves fantastic tater tots all night. (Noc Noc, 1516 Second Ave, 223-1333. 9 pm, free, 21+.)
