The best indian food I have ever had in my life is in san fran, and its DIRT CHEAP. I have spent a lot of time in London (where it supposed to be the best other than india) but Shalimar is the place for me! If you go make sure you try the chicken kofta. The spinach dishes are pretty serious too (saag), along with anything out of the tandor. http://www.shalimarsf.com/
This indian food is so good I have a hard time going anywhere else while I am visiting, but a trip to the french laundry wouldn't go so bad either. The fine dining scene in SF is pretty out of this world. I find myself gravitating to asian food and bread when I visit, rather than pizza. Surprisingly the Mexican food, while way better than east coast fare, is a bit of a let down after spending lots of time in Los Angeles.
As far as pizzerias go I thought pizzaiolo was better than A16, but overall the city is quite underwhelming when compared to NYC. I hear Delfina is the best from some trusted sources, and it might be interesting to you terry, because its not super high temperature pizza. Its more in the coal oven heat realm (although they are using a modded Marsal to reach those temps).
