Matching historical resilience (eg, surviving both the 1906 Earthquake and the 1989 Loma Prieta earthquake's destruction of the adjoining Embarcadero freeway) and persistent visibility along the Market Street corridor up to Twin Peaks - the Ferry Building enjoys iconic status in the city, and has exploded onto the food scene since its latest renovation in 2003.
The Neoclassical Beaux-Arts building is also a transit hub within the Bay Area - connecting the Muni (Buses, Metro and Streetcars) and BART to a variety of Ferry Services.
The Cowgirl Creamery and Hog Island Oysters the Ferry Building offer urban access to Point Reyes farming - along with the Farmer's Market hosted on Tuesdays, Thursdays and Saturdays (the largest). The Vallancourt Fountain across the street can be a good spot to picnic... or along the bay.
Coffee-wise, Blue Bottle has a bar and Pete's Coffee offers free internet with purchase :)
