Restaurateur Sam Fox sold Sauce—the concept he created and nurtured for more than a decade—in 2015. His hope: that buyer Scott Kilpatrick, who founded RA Sushi, would grow it even bigger. Since then, it’s gone from nine to 15 units, with plans to spread in New Mexico and Arizona. Beyond pizza, the fast casual sells pasta, panini, salads and desserts, plus beer and more than a dozen wines.
