Guy Fieripulls up to his latest restaurant—Guy Fieri’s Dive & Taco Joint—in Kansas City, Mo., not in the 1968 red Camaro convertible that’s become associated with his Food Network showDiners, Drive-Ins and Dives, but in a late-model silver Chevy Tahoe. It’s the eatery’s grand opening, and Fieri, 51, wearing dark sunglasses and a camo jacket embroidered with his nickname Guido, happily poses for photos with the screaming fans lining the sidewalk, then gets behind the bar to pour drinks. The next morning, on-set of Triple D, as it’s known to viewers, he reveals that although he played bartender, he barely drank. “I don’t have the liberty of going out at night—two half-shots and I’m done,” he says. “I have to be clearheaded to do this.”

Getting to a place where he can do it all has been an evolution. When he began shootingDiners, Drive-Ins and Divesin 2007, he owned three restaurants in northern California and had two young sons, Hunter, now 22, and Ryder, now 13. Fieri won the hosting gig after taking home the top prize on season 2 ofThe Next Food Network Star. Then, his now-iconic spiked hair and loud shirts were not as well-received: “When I got outta the car to do the pilot, the crew was like, ‘Who are you?’ And I’m like, ‘I’m here to host the show.’ Then the audio guy comes walking up and goes, ‘Who’s that?’ And the crew guy goes, ‘That’s what they sent us.’ ”

Everyone quickly warmed up to their new star, but the schedule took some finessing: “At the time it would take five days to make one show.” Now he and two 10-person crews will film at three or four restaurants in a day, leapfrogging between locations. To date, Fieri has put some 1,200 restaurants in 392 cities on the map—and still manages to take Ryder to school most mornings.

“I give it theTom Bradytheory,” he says. “When you come from a great coach, great ownership, and you come from a great team surrounding you and protecting you, it gives you a chance to throw touchdowns.”

No matter how many miles he travels, Fieri never loses enthusiasm for what he’s doing—or what he’s eating. While fans have speculated whether he’sgenuine about every dishthat makes its way onto Triple D, Fieri relates it to having a few favorite songs on an album, and simply enjoying the rest. “There are different scales of good, great and awesome,” says Fieri. “Not every dish is A+. But if I don’t like it, you won’t see it.”

After 30 seasons on-air, the show is also invaluable to the Food Network, becoming one of their most successful prime-time series. Those closest to Fieri say his success boils down to his authenticity. “I knew him before, and he ain’t changed much,” says friend Sammy Hagar, who met Fieri in 1999 after he won a contest to meet the musician. “He’s really got his finger on a young pulse. He’s more like a rock star than a chef.”

When Fieri isn’t traveling for work, he revels in life at home in Santa Rosa, Calif. Along with his sons, his family includes his late sister Morgan’s son Jules, 19, whom he and Lori have raised since Morgan’s death from meta­static melanoma in 2011. “Our perfect nights are really barbecuing in the backyard and the kids swimming in the pool,” says Lori. “We just hunker down at home. That’s his happy place.” Fieri adds, “I’m so proud of all that these kids get to experience but also at how grounded they’ve stayed. I think that has a lot to do with who I am and who my wife is. We came from very, very close-knit families.”

As his career has flourished—success has brought him around 30 cars (he’s lost count) and his own private plane—he’s come to enjoy wearing one more hat: Guy Fieri the philanthropist. Last year, when destructive wildfires swept through his home state, Fieri drove nearly 200 miles to Redding tofeed the displaced victimsand the first responders.

“There’s nothing in the world that will prepare you for somebody hungry being filled up,” he says. “It’s unfortunately the toughest times in our world where we are seeing the greatest times of our culture.” Hunter joined him on that trip and often shadows his dad on the set of Triple D to prepare for what Fieri hopes will one day be his show. “He’s a great teacher,” says Hunter, a senior at his dad’s alma mater. “When the time comes, I will be ready to roll.”

But that time is not approaching soon. Fieri loves what he does too much: “I’m going to do a lot of these shows. I’ll be in a walker,” he says. “They’ll be getting me out of the senior citizen van, but I’ll still be doing it.”
