Fast-casual restaurant concept Portillo's has announced the appointment of Tony Darden as chief operating officer. With more than 30 years of experience with multiunit restaurant concepts, Darden will play a pivotal role in enhancing operations as Portillo's accelerates its strategic nationwide expansion. He begins work with the brand on December 9.

"I'm thrilled to welcome Tony as we continue to grow Portillo's with purpose," says Michael Osanloo, Portillo's CEO and president. "Tony is a proven leader with an incredible ability to elevate operations while fostering innovation and building inspiring teams. His wealth of experience will be instrumental in scaling our iconic brand while maintaining the commitment to high quality and exceptional guest service that make Portillo's unique."

Darden joins Portillo's from Jack in the Box, where he served as chief operating officer overseeing systemwide operations for more than 2,200 locations across 21 states. During his tenure, he led transformative initiatives, including implementing AI order-taking systems to enhance efficiency and guest experience. Throughout his career, Darden has reportedly proven his ability to drive operational excellence and develop strong teams at the restaurant level. He previously served as president of Mooyah Burgers, and held COO positions at Taco Bueno and Sun Holdings, the fourth largest franchisee in the U.S. Additionally, Darden served as vice president of operations at Panera Bread.

As COO, Darden will oversee Portillo's operational strategy and execution. His core responsibility will be to execute a seamless experience for both guests and team members as the company scales its concept while staying true to its roots. Darden's commitment to innovation and operational rigor aligns with Portillo's long-term target of operating as many as 920 locations, including full-scale restaurants and alternate formats such as Portillo's Pick-Up locations, while preserving the company's commitment to quality and speed of service. In December 2024, the brand will open its first-ever "Restaurant of the Future" in Grapevine, TX, with a smaller, more efficient design, ample seating, and elements such as kiosks and a Grab-and-Go area.

"I am honored to join Portillo's and be part of a brand that has built such a loyal following through its incredible food and guest experience," says Darden. "I look forward to working alongside the team to help Portillo's reach new heights."
