Food is the one thing I'll give SF and the bay area. I've never lived in NYC, but I can imagine it's the only place in the US that comes close. Things are just at another level there than anywhere else I've seen.
Also, California restaurants tend to emphasize ingredient quality over other factors- I don't know what's in a slice of pizza when I go to New York, all I know is it is delicious.
Again, just wildly speculating here
