Following the 1981 publication of his first cookbook, Modern French Cooking for the American Kitchen, which was based on his Ma Maison recipes, Puck opened the restaurant Spago on the Sunset Strip in 1982. Fifteen years later, in 1997, Puck and Lazaroff moved the award-winning Spago to Beverly Hills. It has been recognized as one of the Top 40 Restaurants in the U. S. since 2004. His success enabled him to launch the Wolfgang Puck Companies which includes the Wolfgang Puck Fine Dining Group, Wolfgang Puck Worldwide, Inc. and Wolfgang Puck Catering. The Wolfgang Puck Companies encompass over 20 fine dining restaurants, among the top 40 Restaurants in the U. S. , premium catering services, more than 80 Wolfgang Puck Express operations, and kitchen and food merchandise, including cookbooks, canned foods, and coffee products. He is the official caterer for the Academy Awards Governors Ball, and has parlayed his celebrity into acting; his credits include Frasier, a recurring role as himself on Las Vegas and a cameo appearance in The Weather Man. He also appeared as himself on Iron Chef America: Battle of the Masters, as well as Cooking Class with Wolfgang Puck on The Food Network, and in an American Idol season finale episode where he introduced unusual foods to Kellie Pickler in comic relief segments. He was featured as a guest judge on Season 7 of MasterChef. He also made a cameo appearance as himself on an episode of Tales from the Crypt, and appeared in a TV commercial advertising the state of California (along with famous people such as Arnold Schwarzenegger and Jack Nicholson).
