Need Restaurant Recs for L.A.

Wife and I headed to L.A. for a week. We don’t really have much planned but we both agree that we need to find three really good restaurants of the following categories:

1) steak

2) sushi

3) Korean BBQ

Not necessarily looking for places that are going to be $300 a person so much as places that are unique and delicious

Also open to other restaurant and bar suggestions

Thanks ahead of time.
