The former CEO of Florida, US-based Darden Restaurants, Eugene Lee Jr, has been appointed to the board of directors of fast-casual restaurant chain Portillo’s.

Lee’s background in the restaurant sector includes guiding Darden through a period of substantial growth, increased revenue, and market capitalisation.

His strategic direction as CEO from 2015 to 2022, and as board chairman from 2021 to 2023, was instrumental in navigating the company through the Covid-19 pandemic while maintaining a focus on both team members and guests.

Lee’s association with Darden began in 2007 after the acquisition of RARE Hospitality International. He quickly ascended through roles including president of Darden’s Specialty Restaurant Group.

The decision to bring Lee onto Portillo’s board aligns with the terms of a cooperation agreement previously announced by the chain, and has the backing of Engaged Capital.

Portillo’s board chairman Mike Miles stated: “Gene has dedicated his career to the restaurant industry. His rise from bussing tables to running the world’s premier casual-dining company gives him an understanding of all facets of the business, from how to run a great shift to how to best position brands for growth in new markets.

Portillo’s has also revealed plans to expand its breakfast menu to five new locations in the Chicago region: Harwood Heights, Skokie, Summit, Glendale Heights and the North Side of Chicago.

In April 2025, the chain announced the launch of its breakfast menu in Chicago.
