Economic woes be damned: Judging from the fairly active scene at the Observer’s condo expo at the Puck Building yesterday — apparently, more than 2,000 attendees passed through the doors — New Yorkers are still gripped with condo fever. (That, or they just love swag like free vodka shots, squeeze bottles, and plastic key chains.) Green-minded developments like the Rafael Pelli–designed Visionaire and the Solaria — in Riverdale! — seemed particularly busy. So, did Observer publisher and real-estate mogul — and Ivanka Trump paramour — Jared Kushner, who told "Page Six" last week that he may finally snag a new apartment at the expo, find something he liked? Rumor has it he did, allegedly at a building in the East Twenties. Our bet’s on One Madison or 15 Madison Square North. When reached, a Rubenstein spokesperson for the Observer refused to confirm either of our guesses. —S. Jhoanna Robledo
