The Tavern (map) is a kind of dive-y bar in a hidden pocket between New Hope Commons and 15-501. Although there is, technically, a view of Office Max from the bar’s patio, it feels strangely isolated (and is strangely hard to find) for being adjacent to a giant strip mall.
It seemed like the kind of bar with a lot of regulars and where it would probably be easy to become a regular yourself–everyone was extremely friendly to us newcomers. There are two floors, pool tables, a patio, a dance floor (not in use when we were there), karaoke on Thursdays, several TVs, a 5-foot-tall inflatable bottle of Jagermeister, and good drink specials every night. The highlight for me was the opportunity to relive my glory days via the delightful mid-nineties XM radio station that was playing all night (everyone loves Dookie, right? But if Seven Mary Three is not your thing, there is also apparently a big jukebox downstairs).
I did not get a good look at the full beer selection but there were about 12 taps upstairs. I stopped looking when I saw what I wanted: the Triangle Brewery Pale Ale. This would probably be a good place to hang out if for some reason you really want to avoid seeing any Duke students.
