By Aug 29, 2017 When Sons & Daughters opened at the corner of Bush and Powell in 2010, it was a kind of cowboy in the culinary no-man's land that straddles Union Square and Nob Hill. Next door to Uncle Vito's Pizza and around the corner from Lori's Diner, the restaurant, touting innovative twists on Cal-American fare, was an early comer to the neighborhood that would eventually be home to Del Popolo and, a few blocks away, Akiko's and Liholiho Yacht Club. Nevertheless, its Tendernob address remains an unusual one for the kind of tasting-menu-only experience that has garnered it a Michelin star every year since 2012. Many a commuter has no doubt inched past its modest exterior without ever realizing a guidebook-level meal in progress within, while star-chasing foodies tend to follow the accolades to better known hot spots such as Coi and Benu. Now, a split among the restaurant's partners and an all new menu mean a turning point for the seven-year-old fine dining establishment: Can it retain its star? And, will its name at last carry the significance of its much-heralded competitors?
