Arnold Schwarzenegger's son Patrick has turned businessman and opened his own pizza restaurant in Los Angeles. The 20-year-old college student, whose mother is newswoman Maria Shriver, undertook the project without any help from his famous parents and on Wednesday (30Apr14), he opened the doors to his Blaze Pizza Restaurant location at The Grove outdoor shopping mall. He tells People.com, "It's been my responsibility to oversee everything. I'm the owner, founder, pizza maker, pizza lover and anything else you want to throw on in there." Patrick explains he learned his business acumen from his bodybuilder-turned-actor father and wanted to use it to open a restaurant where everyone could "come have a pizza, get a drink and pay with a 10 dollar bill". He continues, "My dad would have me go and run his charity booth at his body building contest in Columbus, Ohio when I was eight years old. I would sell a poster for $50 and learn, 'How much did that cost?' and, 'What's the wholesale, what's the retail...?' I've always been into (an) entrepreneurial lifestyle. (My dad) encouraged me and so does the rest of my family with everything I do." Shriver was on hand for the grand opening, but Schwarzenegger was unable to attend.
