The only room I do not recommend eating in is the bar area or right off the bar area. Further back upstairs is darker than the great dining area. But if you get a "rail seat" you have a good view of below you . The library is pretty quiet ,,well it's a library , of course it's quiet. Anyway, its not a bad room. But as LBNJNY prefers the :"great room" or the room with the long dining table , it's a really good feel their. reminds me of the Vanderbilt Mansion's great room. So spacious and magnificent.
Any room you choose it will be Ok ,,just not the bar area.
