They have big offices in San Francisco, and also in New York, Dublin, Zurich, London, and various other cities where this stuff matters, though, these days (their Dublin office is right beside the train station that it insists I shouldn't go to, because walking!). You'd think it would've gotten fixed at some point.
I used to work in the Seattle office, but I wouldn't have had the first idea how to get anything like this changed.
Do they develop any products in any of those offices?
All five of the ones named, yes - in fact Zürich is the biggest engineering center outside the US. The majority of Google sites do engineering work.
There is (used to be? I'm not sure anymore) a Maps office in Tokyo too.
