Pittsburgh's cupcake bakeries have disappointed me. Coco's in itself is a cute little place on Ellsworth which I like to go to when it's nicer outside and walk around the shops and foodie places.
Their cupcakes on the other hand were dry (I had vanilla) but my friend had chocolate and liked it a lot better than trying mine. Indianapolis has better cookie places and bakeries than all of the wannabe NYC-cupcake places combined in Pittsburgh.
