Honestly the Saturday market at ferry building is amazing for local produce and artisanal foods but it gets absolutely slammed by 11am. Trust me show up right when it opens at 8am for the best selection and breathing room

Frog hollow farm has the best stone fruit in california and blue bottle coffee before the lines get insane. Parking is a nightmare so take bart to embarcadero station and walk. Bring cash for the smaller vendors who dont take cards
