The Celebrity Chef

The chef who sparked the revolution in Las Vegas dining was Wolfgang Puck. In 1992, he opened the world-famous Spago in the Forum Shops at Caesars Palace. It features indoor patio dining in a casual cafe, as well as a more formal dining room with two private banquet facilities. The menu, which features Puck's trademark American cuisine, changes daily, offering dishes like roasted organic baby beet and goat cheese salad and handmade four-cheese agnolotti. Spago isn't the only place to sample Puck's plates -- visit CUT at The Palazzo for a contemporary twist on the classic steakhouse. From USDA Prime Nebraska corn-fed, 35-day dry-aged steaks to Japanese 100 percent Wagyu Beef, CUT caters to true steak connoisseurs.
