Mexican food.
La Fiesta on Villa street in Mountain View. Very, very special place... been going there for 15 or more years.
The family owns several other places in that area, if they are still open:
Fiesta Del Mar and Fiesta Del Mar 2, and some others.
My favorite, and the favorite of my wife is La Fiesta.
I have a friend that is a retired master BMW tech (highest level training) and he ate there every week.
My wife also recommends Esther's German Bakery:
