I'm 20+ years younger than most of you (about to get my AARP card) but if I recall, in my era there was a fine dining establishment in the east union that was like the Oak Room, and I think it was called the Ivy Room. Though I might be making that up. And I think it might have closed while I was there, possibly when East became all freshmen. But I'm pretty sure I went there at least once, whatever it was called.
Drinking age was 21 during my time and alcohol rules in general were stricter, but if you had a friend working and/or promised a nice tip, you could usually get beer on points there, Oak Room, or at the Central Campus Pub. They all drew big crowds at the end of spring semester when everyone had a lot of points to9 burn.
I will now exit and I don't mean to interfere - I am enjoying lurking and learning more about Duke/Durham before my time.
