The mystery and excitement surrounding Paul Liebrandt’s new venture is a testament to … what? Boredom? Curiosity? The shaggy dog story? The cutting-edge chef has never been a big favorite with the public; he’s more of a cook’s cook, much in the same way that A.J. Liebling was a writer’s writer, or Mark Jackson, a point guard’s point guard. But there’s a hint that his long-rumored restaurant might actually be more than just a rumor, thanks to Bret Thorn from Nation’s Restaurant News, who happened to receive a press kit for the Culinary Vegetable Institute. (What, like you’ve never been to a vegetable institute? Just stay with us here.) Liebrandt is named as having taken part in a chefs summit at the institute; more important, he’s actually listed as “Chef Paul Liebrandt, of his signature Restaurant Liebrandt, opening Fall 2007, New York City.” What? Thorn is on the case, and so are we. More as this develops.
