Best new architecture in NYC

As part of the right-on re-do of Lincoln Center, they've added a high end restaurant with a slanty lawn on the roof. On a visit the other day it was being used by students from the nearby performing arts high school discussing silly ways to remember vocal exercises, Juilliard students hanging out and making out, a little girl doing somersaults, and a sunbathing super model. A few days later, a late-night post-ballet visit turned out to be even more magical, with the city all aglow around this strange little park.
