Restaurateur Keith McNally regrets

British-born restaurateur Keith McNally opened such popular New York City institutions as the Odeon, Balthazar and Pastis. But a 2016 stroke, which caused immobility and affected his speech, led to a suicide attempt two years later. It also led him to take to social media, and pen an irreverent memoir, “I Regret Almost Everything.” He talks with correspondent Mo Rocca about overcoming public embarrassment about his condition, and the importance of having a hamburger on the menu.
