If cost is not important, there is of course a Ruth's Chris in the City, very, very good but pricey even if you order carefully and don't have wine ($50/person and up). Very upscale, mixed clientele, classy place, but no formal dining dress code. This is my place of choice when I want a really, really good steak.
A bit more relaxed on price (unless you order Kobe) is Mortons, also no formal dress code, and Bob's Steak & Chop house (save room for dessert at this one, they have outstanding choices).
Down the peninsula off 101 near the San Carlos Airport (and an exit past a huge MB dealership) is Izzy's Steaks and Chops. Not as good as the other three but relaxed atmosphere and much more affordable.
For seafood and wonderful Italian dishes (best pesto I've ever had) and some great views is Tarantino's on the wharf (McBear seemed to enjoy his dinner there, perhaps he'll chime in). I know you didn't ask about this, but it's my favorite restaurant in the City, and since you have to go to the wharf anyway...
Hope that gives you a few realistic options, do enjoy your trip!
