Just wanted to second that the Golden Ale is a lot more than just "golden"--I consumed two bottles on-site at my post-Great Taste visit this year, and brought a whole bunch home: no more one-bottle limit. That said, I think it's at or slightly past its prime--last summer, it held its own and even trumped Orval, but I'll have to do another side-by-side with this round.
As for Unplugged beers, I enjoyed the Imperial Weizen. The only beer I can compare it to in recent memory is Krunk Monk from Three Floyds. The latter had nice, popping flavors but was quite thick and sweet. Imperial Weizen is like a better attenuated version, though the alcohol is noticeable.
Agreed about Cran-bic, although it definitely has some lambic features. A mild intro to "barnyard" and "horseblanket" for those disinclined to wild fermentation. Good fruit character--NG has a magic touch with fruit--and a vast improvement over that other "cranberry lambic"

and with (I thought) more lambic character than Lindeman's various fruited versions.
I'd also picked up some Abt this round. It was fairly good, but side-by-side with Dieu du Ciel's Rigor Mortis, it lost out by a bit. It was, however, somewhat cheaper than both the Dieu du Ciel and your average Belgian in that style.
All this goes to show that trips to the brewery itself involve spending way more money than anticipated
