Kitty Hawk,
There are many, many good choices in the Los Angeles area. Other than tomato sauce, is there anything else your boss or your clients would be partial to? It would help in narrowing it down to some specific recommendations based on food preference rather than the scatter gun approach.
Also, will you have a car, and are you willing to navigate Southern California in search of a good meal? Otherwise you'll want to concentrate your search in the Universal City/Toluca Lake area.
