Gimme a break!
First, it's not Frisco or San Fran. It's SF or San Francisco or The City. As to the wharf: The attractions are typical of AnyCity, USA (Hard Rock Cafe? Please). And while there is good seafood to be had there, it's way overpriced and usually mediocre. In a city known internationally for its creative food, top-notch chefs, and sustainable restaurants, you're wasting your time and money down there.
Next time you visit, try venturing out of the wharf and see what makes SF an incredible place to live and visit. Take a hike at Fort Funston, ask a local for a good neighborhood restaurant rec, take in one of the impressive farmer's markets. And if you decide not to, if you think the wharf is "where it's at," then thanks for giving us your money (and know that we actually prefer to keep you confined in that terrible place).
P.S. It's often quite cold here in the summer, and nothing spells tourist like shorts on July day.
