Forget Rice-a-Roni, the original San Francisco treat was Ghirardelli Chocolate. Founded in 1852 by Italian immigrant Domingo Ghirardelli, it remains the longest continuously running chocolate manufacturer in America. Serving locals and tourists San Francisco-themed sundaes, shakes and cocoa bars at their original landmark location for years, you can now get your favorite decadent ice cream desserts in downtown SF’s Westfield food emporium. Craving something a bit warmer to melt the fog? Opt for the Sea Salt Caramel Hot Cocoa with a milk chocolate caramel square and a whipped cream topper.
