I've been gone from the area too long to be able to really help a friend looking for the following:
A restaurant for lunch or dinner for 10-15 people. Cost of $30-40 per person not including private dining room cost (private dining room not required.) Doesn't have to be family friendly but that would be nice. A restaurant where alcohol is not the focus, it can be there but not as the focus. Ambiance is important.
Once of the first places that came to mind was Beechwood Restaurant in Marina Del Rey.
Thank you in advance for your help.
