A taproom serving only local craft beer is a nice concept, but it would work a lot better in a city with a better brewing scene than Pittsburgh, which has plenty of decent breweries but no real standouts. I found nothing exciting on the list when I visited, and several of the better local breweries (Full Pint, Draai Laag) were not even represented.
Don't get me wrong; IBC is a classy bar and a huge improvement over Fanattics. If you're looking for a place to discover local craft beer, you can do no better. As a hardcore beer nerd, however, I want something special if I'm going to pay upwards of $6/pint.
