Phoebe Washburn, Nunderwater Nort Lab

The downtown half of Washburn's doubleheader, here and at Mary Boone Gallery near 57th Street, features as its centerpiece a wooden structure in which lunch will be prepared and eaten daily. But not served to gallerygoers; they must remain content to observe the proceedings through "wormholes." If you get hungry easily, we advise getting something to eat beforehand.
