San Francisco is a city transformed by programmers, staggering wealth and start-ups. But the Michelin-starred chef Dominique Crenn remains attuned to the sense of possibility that has long drawn artists, innovators and pioneering spirits to the City by the Bay. Ms. Crenn, the first woman in the United States to receive three Michelin stars for a restaurant, arrived in San Francisco nearly 30 years ago, after earning a degree in international business in her native France. “I was at the airport and I didn’t know anything about San Francisco. I got out of the plane and I felt something powerful. And I remember thinking, I’m home,” said Ms. Crenn, who grew up in Versailles and spent summers in Brittany.
