I went there once with some work colleagues. It is high end Mill Valley dining. The room is posh. There is a fireplace which is nice to sit by during the colder weather.
The menu is short, with nothing really distinctive. But I remember that all our dishes were very good and well executed. I had the Kobe burger and it was a great burger.
I also remember that our server was excellent.
It's a steak and martini kind of place. I guess the bar scene is popular with a certain Mill Valley demographic.
