There are cookbooks and there are biographies, but rarely are the two combined as they are in Personal Favorites: The Chefs of Las Vegas. The very concept of Las Vegas dining has experienced unprecedented change during the past decade. While a few chefs were keeping the faith in scattered locations in some of the city's resorts and a few neighborhood locations, the gambling mecca for many years was known primarily for food for the masses, cheap and in huge quantities. Powdered scrambled eggs, overflowing buffets of steam-table staples, oh-so-skinny prime rib with watery mashed potatoes and rubber shrimp were the stock in trade. That began to change in the '90s, as a steady stream of celebrity chefs and lesser-known but equally talented lights began a parade to the city. It continues today, when visitors to Las Vegas can win at both the dining and gaming tables. Personal Favorites takes a look at 13 men and women who have helped make the city a world-class dining destination. These are their photos, their recipes - and their stories.
