There are some things you have to drive for, like great dim sum, but the great Middle Eastern and Japanese food more than makes up for it.
Two of my favorite restaurants in the world:

monte alban is great but not for tacos/burritos.
That's the perfect California response and it contains significant cultural wisdom that answers many confusions in this thread.
On the other hand, ones favorite place for these things might well be an hour away. I live in West LA and my favorite Mexican food is in Eagle Rock and my favorite mediterranean food is in Orange County...
I commute most days, usually several miles. The only time I prefer car or train is when its raining, which is rare.
