You may not want to take the little kids into the 'live markets' (butcher) ,,,but don't miss the fortune cookie factory on Ross Alley, since fortune cookies were invented in SF , by mr. hagiwara, a japanese-american, at golden gate park in the japanese tea garden in 1894 !! during the first world fair in SF.
Also, built on sand underground parking garages,,,one of the fish stews chippino, levi's the gold rush tents-cut-into-'jean' genoa sailor baggy pants,,, the martini whatever nyc says,,,1874 cable cars on clay street and nob hill,,,
Enjoy !!
Recommend you ride a cable car on the safer right side boarding at union square vs the 1-3hr line at market street,,,walk for free across the golden gate bridge about a mile vs pay $25 to go direct to jail alcatraz,,,and see 'beach blanket babylon' sold out for 25 yrs comedy on green near columbus in the former italian neighborhood n.beach !!
