Eye surgeon Jeff Dello Russo celebrated his 40th birthday this month by moving most of the furniture out of his loft on East 20th Street into storage to create a dance floor. Chef Rocco DiSpirito decided the sangria needed a kick, so he spiked it with Grand Marnier. Word spread and models started crashing.
