Walnut Creek - Sunday lunch?
Heading to the Del Valle on Tice Valley Bl -- coming from Marin (via SP Dam Rd?) -- any place special or very okay on the way?
Lafayette might be more on the way. Not sure what you are interested in, but there are some options there.
Of the links I listed, I haven't been to Metro, but all the other ones are good for different reasons.
