I love Old San Francisco!.
A great resturaunt with a fantastic ambience... Candles on ever table and dim lighting make for a romantic experience, but I have seen lot of families and large groups there, too. The steaks are succulent and melt-in-your-mouth; you almost don't need the knife, especially the ribeye. WHen sat wonderful fresh bread and a decadent block of cheese are palced on the table, and if you are not carful, that can be a meal all by itself! I highly reccomend the French Onion soup - to die for
