Since East End Brewing Company has moved to a new location, it's time to update my review. This is still some of the best local beer available in Pittsburgh, but now rather than having to sample it in a cramped hallway, you can enjoy the expansiveness of the new space which is shared with the Commonplace Coffee Company. Sidle up to the large bar for samples of whatever is currently on tap - the old standards plus rotating seasonal beers, ginger ale, and root beer. Purchase a reusable half-gallon glass growler full of beer, and then bring it back for refills.
In addition to beer on tap, other merchandise available includes glasses, T-shirts, knitted caps, and pre-bottled specialty beers. They've also started offering a biweekly tour of the brewery which is excellent and highly recommended. This is one of the gems of Pittsburgh. Check it out.
