LOS ANGELES: Hollywood actor Bradley Cooper, who worked in several restaurants before hitting showbiz, says he learned a lot about the culinary world through a hard way, but loved every moment of it. “I worked in kitchens and I was a busboy in a Greek restaurant when I was 15 and I was a prep cook in another restaurant when I was 18 for three months, where I was literally prepping all day long, the lowest in the totem pole of the brigade. “I felt like it was very hard, but I learned a lot and I felt the pain of being berated by the chef and I saw the hierarchy and the stress and the pressure. But I actually did thrive there and I loved it,” Cooper said in a statement. In his forthcoming film Burnt, Cooper plays the role of Adam Jones, a chef who destroys his career with drugs and his high-handedness. In the John Wells directorial, his character cleans up and returns to London, determined to redeem himself by spearheading a top restaurant that can gain three Michelin stars. The American Sniper star added that he respects all the chefs in the world.
