George A. Kalkounos, a longtime Chicago-area restaurateur and founder of the Chicago Prime restaurant group, passed away February 17, 2026, at the age of 75. According to family members, he died peacefully with his wife, Maggie Kalkounos, by his side.
Kalkounos emigrated from Greece, first settling in Brooklyn before building his career in Illinois. Through decades of work in kitchens and dining rooms, he rose to become a respected figure in the region’s hospitality industry. His portfolio included Chicago Prime Steakhouse, Chicago Prime Italian, and Five O’Clock Steakhouse, along with several banquet halls and dining establishments that became staples in suburban communities.
Online tributes from friends, customers, and local officials reflect a consistent theme: Kalkounos made people feel welcome. Commenters described him as affectionate, generous, and deeply invested in both guests and staff. Many shared memories of personal greetings, warm embraces, and the sense that his restaurants were places of belonging rather than simply businesses.
His passing also resonated within local government circles, as he was the father of Palatine Township Supervisor Andy-John Kalkounos. Township representatives publicly acknowledged his influence and offered condolences to the family.
In keeping with his commitment to mentorship, the family is encouraging donations to the George A. Kalkounos – Chicago Prime Restaurants Endowed Scholarship Fund at Harper Community College, supporting future culinary and hospitality professionals.
Services will be held at Ahlgrim & Sons Funeral and Cremation Services in Schaumburg, with funeral liturgy at St. Nectarios Greek Orthodox Church.
