We ate at California Grill a couple of weeks ago. We've eaten there quite a few times in the past. I have to say, it was one of the best meals overall that we've had there (and definitely on this past trip overall!) Everything was outstanding~ the food, service and overall experience. I'm pretty picky and can say we've had some not so stellar visits in the past, but it seemed to be hit or miss with some great experiences sprinkled in. It's my DS' favorite restaurant which is why we return again and again, and usually go to at his request. My observation is, that our experiences have been different depending on the time we go. We find early reservations (5pm) have always been our good experiences vs. late reservations (9pm), not so good. It is pretty quiet early on, and the servers and kitchen seems to be more attentive to details at this time. Later on seems to be rushed, crowded and full of tired park families. (Just our experiences...)
This past visit, (early, 5pm) we were seated at a beautiful window table, the sun was just setting and made for a very beautiful view. Our server was *wonderful* and very attentive to our needs. She just seemed to know what we needed and when. I wasn't sure about wine selections, so she had me try a few to find one that I enjoyed. (By the glass~)
My DD has several severe food allergies and is picky as well, so our server (at her suggestion) had the kitchen come up with something that was safe AND appealed to my DD's likes as well. That is above and beyond to me~ and very appreciated!
We enjoyed flatbreads, cheese plate (although not the one that has hints of "cave and grass"... it tasted like, well, cave and grass

), goat cheese sonoma ravioli (I could slurp that tomato broth alllllll day

), Oak fired filet, chicken, creme brulee, sundae sampler.... wine, hot tea ==== all excellent! (and love the bread and butter they serve too...)
Although our meal did take 2 hours, we were able to come back up for fireworks, it was an easy process to return. I like that better than interrupting the meal for fireworks, which we've done as well. Even though they time food so you're not served right before the fireworks, I still enjoy being done with dinner first.
The bill can definitely add up quickly if you are not on the dining plan. I didn't mind it because everything was so good. However, if it wasn't as good, I would have been annoyed with how expensive it is for a less than stellar meal. So I can see how people may be less than happy if their meal wasn't as good as they expect it to be.
I hope you have a wonderful anniversary dinner there!
