Over in the Flatiron District, rooftop bar 230 Fifth is set to reach a little higher in the air with an unusual publicity stunt. On June 20, the bar will play host to an 150-member acrobatic troupe from Spain to build an 8-story human pyramid on top of the roof. And, they won't be wearing harnesses (take that guy who's walking across Niagara Falls on a tightrope). It's supposedly breaking some sort of World Record, but we think the real reason to stop by is that it looks pretty cool. The Tower building starts at 8:15 PM (212-725-4300).
