From NY Observer

It’s more or less an open secret, but we’ve learned that the Top Chef cast has definitely been living for about two weeks now in a terraced duplex penthouse in Williamsburg overlooking McCarren Park. So far, the chefs have pretty much kept to themselves, said an extremely well-placed source, leaving around 8 or 9 in the mornings for a soundstage in Greenpoint and coming straight back in the evenings…. 

Though the source would not say which of the two “identical” parkview penthouses the cast is living in, a 1,368-square-foot, 16th-floor unit was sold in April for $1.4 million, according to StreetEasy. (Meanwhile the neighboring unit, 16A, is in contract for $1.295 million.)

According to the duplex floor plans on the 20 Bayard Web site, the first floor has an open-air kitchen, foyer, eating area and living room–with a balcony–and floor-to-ceiling windows overlooking McCarren Park and Manhattan. …

So far the cast has remained pretty incognito. Few people from neighboring buildings were even aware Top Chef was shooting in Williamsburg.

“No way,” said the cashier at Urban Rustic, an organic market down the street, who is a fan of the show. “That’s awesome.”

So will the cast do any shopping there?

“That would be cool, but I doubt it,” the cashier said. “They usually give them a budget.”
