Eat, an Environment by Allan Kaprow, was presented during the mornings and afternoons of the two last weekends in January, 1964. Prospective visitors made reservations through the Smolin Gallery and were given directions on getting to the caves in the Bronx in which the Environment was created. Only twenty reservations were made for each one-hour period in an attempt—almost always successful—to forestall overcrowding and keep free circulation in the space.

After entering an old building that fronted low cliffs, the visitor walked through several corridors and doorways and finally came to the Environment. The rock from which the caves were carved had been somewhat incompletely covered with white paint—the place had once been used by the Ebling Brewery—and age and seeping water had created a sense of decay. Black charred wooden beams stood propped against the walls in several places.
