<p>Dont miss the Ferry Plaza, especially the Saturday farmers market. Another vote for Boulavards , not far from the ferry beuilding and VERY romantic if you can get a table with a view of the bridge. Also seconding the great public transportation, the great weather in August, chowhound.com, and also Opentable.com, for reservations, reviews, and menus. If there is time, consider a day trip to Napa. NOT reccomending restaurants in Chinatown, but it is fun to visit.</p>
