A couple additions:
I really enjoyed Rockbottom. The IPA was excellent. The White IPA was disappointing and the others I tried were not so special, but I could see there is some experimenting going on. The food was also not so good, but I found pub food generally disappointing in Halifax. What I did like at Rockbottom, in addition to the IPA, were some great little bands and the knowledgeable staff.
Another decent place was Maxwell's Plum. They advertise 60 beers on tap and look pretty much like a college bar, but they had an excellent local tap selection (lots of Garrison, Propeller and Pump House) and some o.k. imports. Serving sizes were smallish 12 oz, but the happy hour prices were great. Again, great staff that knew their beer and forced samples on us.
I also watched them really help educate and move some newbies along. They did some good PR work for the local breweries.
Propeller was pleasant, but nothing on the tasting tap I had not already tried at Maxwell's Plum.
Garrison has a great tasting room in their store. I didn't take the tour since I already know how a brewery works and preferred to chat and sample with the staff. BTW, I think everyone that works there is from Toronto.
Rogues Roost is a little dingy and the beer is good, not great. I'd say if a brewpub like that moved into your neighbourhood, you would visit often, but not necessarily rave about it. In other words, on par with many small brewpubs.
Had some pretty decent BBQ at a place called Q. Some Garrison on tap rebranded as a house beer. Typical of many BBQ places, the sides sucked. Go for the meat.
Henry House was slammed when I went with some Dalhousie event, so I can't comment.
Brands are for cattle.
Fans are cash cows.
The herd will consume until consumed.
