Ana Mandara Restaurant ***
This is NOT a "Vietnamese" restaurant in the normal sense. It is a "fine dining" establishment in a touristy part of San Francisco. Despite that, the food I had (fried lobster ravioli appetizer, tournedos of filet mignon and scallops with black rice) was superb. It is priced well beyond my normal range so I doubt I will ever return, but if you have the cash, and the inclination for well prepared, surprising dishes in a grandiose environment, without having to get reservations, Ana Mandera is top notch.
