Named for the four tycoons who built the Central Pacific Railroad (C.P. Huntington, Leland Stanford, Mark Hopkins, and Charles Crocker), the Big 4 Restaurant is a high-class affair, replete with vested servers who quietly appear when a wine glass needs to be refilled. Green leather booths, dim lighting, dark wood, and railroad memorabilia on the walls give the impression of a tavern, but this is a fine-dining institution helmed by chef Gloria Ciccarone-Nehls, known for her specialty in exotic wild game.
