Hmmm, we are going to have to check your credentials. In your opinion what is the best Chinese restaurant in either LA or SF?
Seafood: Newport Seafood(SGV). The restaurants listed above are decent for the Bay Area with Mayflower a notch or two below.
Best Taiwanese street food: Sin Ba La (Arcadia). Southland Flavor Cafe(Cupertino)
Lastly, in LA, the 626 Night Market is lots of crazy street food.
(Bistro Na is great too.)
