I recall going there about five years ago and thinking it was pretty good. I didn't recall the high prices and small portions.
I thought it would be nice to hit the Getty in the early evening and have dinner at the Restaurant around 7. The service was friendly enough and very attentive but go less so as the place got more crowded (understandable). We didn't have an appetizers, they weren't conducive for sharing. For my main, I had a duck dish that was flavorless. My husband (an Aussie) was thrilled to see barmundi on the menu, which was tasty but the portion was tiny. It came with some gnocci, which I didn't even see him eat, there were that few. The desserts were not bad, I had banana cream pie with some peanut butter ice cream and DH had a peach panna cotta. The entrees were $29 each, steep for a small portion with little flavor or sides and the desserts were $8.50 each. With a coke and one coffee, the total bill was $88 (not including tip). I might consider going back for a more reasonably priced lunch with someone from out of town but not for dinner.
