NYT 36 Hours in Silicon Valley
The New York Times travel featured Silicon Valley in their "36 Hours In" article this week. It's worth checking out. They list St. Michael's Alley and Calafia for dining which I would agree with. I think they try to give you more of a locals flavor than special event type of places and since I've eaten at both of those restaurants in the past two weeks I would agree.
I also like my taste validated in the NYT.
