I am looking for a job for a french man, in a restaurant in Sacramento
starting this November/December.  He has years of experience in the
restaurant business and would like to persue a career in California. 
He will be residing in Sacramento, California, so he would like to
find a restaurant to work in, in the sacramento, Davis area.

Hi birdie-ga,

Since your friend has extensive experience, he should be able to get a
good job at a better restaurant.  Citysearch has lists of the best
restaurants in many different categories:

Here's a link to a list of top award-winning restaurants and a search
engine by neighborhood for restaurants in the Sacramento area:

California's official resource for job seekers provides much useful
information about seeking employment in California:
"EDD - Job Seekers", California Employment Development Department

Particularly appropriate to your search is the CalJOBS database. 
After creating an account, you can search through listings for any

More particular to Sacramento is the Sacramento Bee's job listings,
which are available online:

If you need more details, feel free to request clarification.
Good luck with future searches!
