We have been several times, the most recent was last month. The wine list is extensive and the prices are on the high side. The wine service is only as good as the Som assigned to your table. (Unfortunately not great at our last visit). There is no pairing. There are wines by the glass. They will send you the wine list ahead. Rule of thumb is it's not nice to take a bottle they sell.
And to answer your last question, GA is about right- We did one foie, 2-3 glasses each and split a bottle with the other couple. The wine was in the good not wow category. Tab was $1700 for both of us.
A word of caution- they add the tip, which is explained on the website and at reservation, but it is not obvious on the check. They also leave a space for gratuity open, so you can tip additional. Makes it more confusing.
