Au Bon Pain: The once-trendy bakery café chain is no longer quite as popular as it used to be with 45% unit decline last year. In 2021, the former Panera Bread sister brand was sold to a new owner (Ampex, a Yum Brands franchisee), and since then Au Bon Pain has shrunk to less than half the size it was under Panera ownership (115 to 55 units).
