Because I live half of my weeks in Los Angeles (about a mile from Universal City) and I eat out at almost every other weekend, I know restaurants. There is everything from okay to outstanding restaurants. One of your best guides would be actually Los Angeles Magazine, because its rare that restaurants don't meet expectations in their guide.
I have tons of favorites. are you looking for a fun experience, a business experience, a casual experience, what? (I know its your boss). Also, any preference on cuisine? Steak, Seafood, ethnic, etc.? Price?
There's tons in every category.
