I definitely left my stomach in San Francisco; everything from wine to pizza to salted caramel ice cream to crudo to a mortadella hot dog. And, there are many places I didn't get to on my list.
salted caramel + strawberry balsamic: Bi-Rite Creamery in the Mission
menu + refreshing hibiscus drink: Nopalito
Omnivore Books: tiny shop full of cookbooks, old and new
Boccalone in the Ferry Building: Chris Constantino's shop devoted to tasty pig parts
Tasting menu + wine pairings: Commonwealth in the Mission
Pot and Pantry: store sells gently used high end kitchen gear and offers recreational food classes
Marin County/San Rafael Farmers Market: 3rd largest market in California
