If you want a bigger place maybe Palomino in the Village. If you want something more intimate then Sprazzo would be a good choice. Just south of the Village on Westwood Blvd. across the street from Borders Books.
I second Napa Valley Grille. When I worked in the area, I took many clients to lunch there. Nice booths, quiet, good service (didn't hover over the table unnecessarily so talking shop with the client was not constantly interrupted,) and good lunch food.
