The soba future of 66 is uncertain.Photos: Getty ImagesIs Jean-Georges Vongerichten reconsidering plans for a soba restaurant? We’re hearing from sources within the Japanese restaurant community that Vongo’s deal with the Matsushita brothers has collapsed. The idea was to turn 66 into a Matsu Gen, a temple to the art of buckwheat noodles. The place was slotted to open this spring, but expectations are low. So will the 66 space get a new concept, or will Vongerichten do a soba restaurant with somebody else? We’ll let you know when we hear.
