I've stopped at Paddy Cake Bakery several times since moving to the East End of Pittsburgh. While the selection seems more geared towards sweet baked goods then breads, it's still extremely well stocked and the staff is some of the friendliest I've met in Bloomfield. I'd love to see some more bread, roll, bagel, etc options as I rarely partake in sweet baked goods. The hours, while not really accommodating for someone who leaves for work at 6:50am and doesn't get home till 6:10pm, are still long enough to be accessible to most people.
I will say though that while the selection of sweets is large, none of the things I've tried have really struck me as unique to this bakery or to the East End. I think that if the bakers in the back took some time to develop some signature items that would make them stand out from the general bakery and I'd most likely not stop anywhere else.
