A Change in Pittsburgh's Lineup

Heading through western PA a couple of weeks ago got me to thinking. A few closures and an unpopular hefty drink tax in Allegheny County. What's going on? Shouldn't it be the Pirates lineup that is getting a bit of a shakeup? The craft brewing scene, gaining strength in recent years in the Pittsburgh region, appears to be going through a bit of a readjustment. But, I don't live in the area. If you are, let me know if this is something other than a few unsuccessful business models falling by the wayside.
