We're taking an elegant and very sophisticated elderly lady to dinner in a few weeks. Although she has more brain cells than 99% of people half her age, at 95+ years, she has become increasingly frail. We've taken her to the Peninsula dining room and Melisse many times...and although both are really quite perfect for her, we'd like something different. We need a place with easy access (no, or very few steps), reasonably quiet, very nice ambiance, with very good food and service. It needn't be as elegant as the Peninsula or Melisse, but it must be very nice. We'd like it to be somewhere between Beverly Hills/West Hollywood and Santa Monica.
