The BreadWorks bakery is the best! It's not a "bakery" of the type that makes cupcakes, this is bread-only. It's serious bread, with artisan loaves of sourdough, rye, pumpernickel, French and so forth. They'll slice the softer ones like pumpernickel on request but not a hard-crusted bread such as sourdough. I've had great breads in San Francisco, NYC, Paris, Montreal and other major urban centers, this is the only place in Pittsburgh that is up to those standards. It's very similar quality-wise to Iggy's in Cambridge MA if you're familiar with that.
