Make a movable feast of a San Francisco stroll by munching your way through the new FERRY BUILDING MARKETPLACE at the landmark 1898 Ferry Building, its vast skylit hall now polished to the tune of $90 million. Picnic progressively on artisanal loaves from Acme Bread Company, dairy bar cheese at Cowgirl Creamery, and bivalves at the bayview counter run by Hog Island Oyster Company. Or break for sit-down seasonal fare at MarketBar cafe.
