Panera Bread/Au Bon Pain: Ron Shaich

In the early 1980s, Ron Shaich bought a small, struggling Boston bakery chain called Au Bon Pain, and built it out to 250 locations nationwide. Ron then saw an opportunity to build something even bigger: Panera Bread. It was the start of "fast casual" – a new kind of eating experience, between fast food and restaurant dining. Today, Panera Bread has over 2,000 stores, and $5 billion in annual sales.
