Best quiet restaurants in LA?

I tried looking up this question on this subreddit and found a thread where someone posed the same question... but they got decimated for judging people's suggestions as "too loud" based on the look of them lol.

So I'm here to pose the question again! What are some of the best restaurants in LA where you don't have to yell to hear each other? My family would like to celebrate my elderly father's birthday, and we always run into the issue of not being able to hear him when we go somewhere nice. Thanks!
