Grand Central Terminal Interior.

For the Oyster Bar at Grand Central Station, Guastavino Jr. devised a series of vaults of cream-colored tile to create a space that was both intimate and expansive. The vaults endured the ultimate test in 1997 when a fire ravaged the popular restaurant. Thousands of tiles delaminated from the ceiling and had to be replaced, but engineers cited the results of the Guastavino Company’s fire tests of a century earlier to prove that the basic structure was still sound. The bar reopened only 12 weeks after the fire.
