Co-Chef/Owner, Border Grill Restaurants & Trucks, Socalo, BBQ Mexicana, and Pacha Mamas

Mary Sue Milliken is a James Beard and Julia Child Award-winning chef, cookbook author, activist, and media personality best known for her modern Mexican concept, Border Grill restaurants, trucks, and catering, which she runs with her business partner Susan Feniger. Now with locations in Los Angeles and Las Vegas’s Mandalay Bay Resort and Casino, Border Grill continues to serve street food-inspired regional Mexican cuisine with a commitment to sustainability and conscientiously-sourced ingredients. In 2018, Milliken and Feniger debuted BBQ Mexicana, a fast casual eatery now with four locations in Las Vegas; in late 2019 the chefs opened Socalo, a California canteen and Mexican Pub serving seasonal SoCal Mexican fare in Santa Monica; and in 2021, the duo launched Pacha Mamas, featuring seared skewers a la plancha, now with three locations in Las Vegas.

After graduating from Washburne Culinary Institute in Chicago, Milliken worked her way up and became the first female chef at Le Perroquet in 1978—where she soon met Susan Feniger. Following, she cooked at the woman-owned, two-Michelin-star Restaurant D’Olympe in Paris, before rejoining Feniger in L.A. to launch City Café in 1981, applying French techniques to traditional dishes from around the world. The culinary pair found further acclaim with CITY Restaurant in 1985, and captured the hearts of Angelenos with Border Grill’s ’85 debut. Winning the James Beard Award in 1985 was the first of many honors including lifetime achievement awards from Women Chefs and Restaurateurs, CA Restaurant Association, and Menu Masters Hall of Fame. Most recently, Mary Sue was the recipient of the Los Angeles Times’ annual Gold Award and the Julia Child Award.

Mary Sue has co-authored five cookbooks, co-starred in nearly 400 episodes of the Food Network’s “Too Hot Tamales,” and co-hosted a food centered radio show for over a decade in Los Angeles. She competed on season three of Bravo's “Top Chef Masters," winning $40,000 for her charity, Share Our Strength, that aims to end childhood hunger in America.

Mary Sue has served as fundraiser, board member and advocate of Share Our Strength since 1987 and also serves on the Board of Trustees for the James Beard Foundation. In 1993, she joined a handful of colleagues to create two organizations: Women Chefs & Restaurateurs, an organization promoting women’s education and advancement in the restaurant industry; and Chefs Collaborative whose mission is to inspire, educate, and celebrate chefs and food professionals building a better food system. Most recently, she co-founded Regarding Her, a non-profit to provide women owned restaurants in LA county business grants, mentorship and resources in response to Covid's crippling effect on the industry. Additionally, Mary Sue served the U. S. State Department as a member of the American Chef Corps, working in Pakistan, Morocco, Jordan, U.K., India, Malta and Italy to promote diplomacy through food. She is passionate about food policy, working alongside the Monterey Bay Aquarium as a member of the Blue Ribbon Task Force, a panel of culinary leaders committed to innovative outreach to promote sustainable seafood, LA Food Policy Council, Pew Charitable Trusts, Oxfam, and others to help shape sustainable food systems.

Mary Sue spends the majority of her time thinking about food and cooks 7 days a week, whether at one of her Border Grill restaurants, Border Grill Truck or at home with her two sons and husband, architect Josh Schweitzer
