This "pop-up nightclub" in a long-defunct church is essentially a massive Halloween weekend blowout, with both nights boasting full open bars (for a price) and Vegas-style entertainment: Friday night's got a 1920s-style big-band with flapper dancers and a faux-vampire wedding, while Halloween itself's got a performance from "I Love College" rapper Asher Roth, who'll be dressed up as a one-hit wonder.
