For a newer course, Castle Pines has a great locker room with a large fire place, oversized lockers, the best milk shakes in memory and a bartender (Tom) that can remember your name, what you like to drink and when you last played the course even after only playing the course only once. The ambiance and attention to detail seems like you are in someones living room.
For classic courses, Seminole, Winged Foot, Merion and R & A are great.
Cheers,
