Not sure about bars and what they have on tap because I don't drink in bars as a rule. As far as breweries that used to be hot, I buy more of their beers than new fangled ones. Stone, Sierra Nevada and Lagunitas more than any others.
My youngest daughter lives in Salem, OR and has worked her way through her post-graduate studies in a small brewery/restaurant. She and her other half are both beer geeks, so when we visit them they always have a plan to hit a bunch of brewpubs and/or tap rooms. The last couple of visits we have gone to Newport, OR and enjoyed Rogue's food and beer. Also on these trips we ventured north a bit and visited both Pelican and Rusty Truck. While I enjoy beers from the latter 2, I prefer Rogues offerings.
Last summer we spent several days in Bend with the kids and visited many of the local breweries there. Again, I enjoyed the variety of offerings, but still found my preferences to include Deschutes.
All in all, I believe it's all a matter of personal preference. Before discovering craft beer in about 2007 I was an MGD guy, so maybe still enjoying the variety more than many.
