Many years ago, the company I worked for took our (very small) team to dinner here after a great month. I will never forget that meal as it was the very best dining experience I have had in my entire life. (And I've enjoyed some pretty grand dinners.)
I won't pretend to remember everything I ate but it did include an aparteif, app, wine, dessert, etc. Nothing was skipped and every part of the meal was beyond words.
I particularly remember the service being several steps beyond what I had known to be "good service". (When a team of staff come out and sync the placement of your table's plates? Yeah, that is beyond good service).
Ambiance, as you can imagine, is something special.
No, this kind of dining is not about value so you'll need to save up for it. But do treat yourself at least once in your lifetime. Remember this place when you and your significant other have a special birthday or anniversary to celebrate.
