Fodor's Expert Review United Nations Plaza
Locals know this plaza for two things: the farmers' market held on Wednesday and Sunday—cheap and earthy to the Ferry Building's pricey and beautiful—and the many homeless people, a consistent presence despite numerous efforts by the city to shunt them aside. Brick pillars listing various nations and the dates of their admittance into the United Nations line the plaza, and its floor is inscribed with the goals and philosophy of the United Nations Charter, which was signed at the War Memorial Opera House in 1945. The food-truck gathering Off the Grid (offthegridsf.com) livens up lunchtime on Tuesday and Thursday.
