I just want to warn you that we did almost the last reservation at Ohana one time. The food was excellent, but I was quite irritated that the staff felt comfortable to sweep around us while we were eating. To me, that is inappropriate when I'm paying $50 a person for dinner. We find that middle of the night was our favorite.
I would certainly hope they would not feel comfortable cleaning around you at California Grill, but you never know. I just know it would really destroy all the romance and magic for me.
