I should be able to make it on the 7th. It's in my calendar now.

For seafood or sushi, I'd suggest:

Zuni - one of the places that defines California cuisine and a personal favorite. Great oyster bar with huge selection. Terrific non-seafood menu, too. On Market Street about a 10 minute cab ride from downtown hotels.

Tadich's - downtown SF, very old time SF type of place. They have sand dabs, hangtown fry, menu like that. Waiters that have been there b100 years. Might be a little difficult to get a table a little earlier on.

Hamano Sushi - best sushi I've had in San Francisco. Great choices, always fresh, always packed with locals. Far enough from downtown and tourist ghetto and tucked away in Noe Valley neighborhood which fortunately most out-of-towners don't bother with. 30 minutes from downtown, easy Muni (underground) ride + 3 block walk.

Delfina - the hot new seafood restaurant in the Mission District. I've never tried it but have only heard great things about it.

Carta as jet'dillo mentioned is always good and I am friends with the owner. www.carta-sf.com for them menu. A few doors down from Zuni.

All of these places will run $25-$40 per person not including drinks, tax and tip.

spiff, do any of these appeal? I would be glad to make arrangements at any of them or help out in any way.
