No Red O recommendations lol? As for Newport I agree with Side Door and A Restaurant (plus A has a pretty decent happy hour). The vibe at Sol just didn't do it for me, something about Sol I don't care for but can't really put my finger on it.
Santa Ana, I would add Chapter One to your list for the unlimited
mimosas with four juice mixers on Sunday brunch. It's $6 and the
musician they have perform on Sundays is really good!
Agree with Sea Legs and the Corner for HB.
I live in Costa Mesa and I don't like your selections. Memphis? Maybe I'm missing something. Wine Lab at the Camp is a pretty good spot.
