I stopped in to buy birthday cupcakes for a friend, but ended up getting brownies and chocolate croissants and lots of bread. I try to stop in here once a week for my bread now. They have a lovely selection of breads, from walnut raisin to ciabatta. So far, I'm not a fan of the chocolate croissants, but the breads are scrumptious.
The employees there are really nice and make helpful suggestions. The prices are pretty good. The same kind of bread is the same price at Giant Eagle (about $4-5), but I think the one at Allegro is fresher. Plus, I like the idea of supporting a local bakery that makes small-batch breads. There is also a shelf by the door that has day old bread for 40% off. I got one once and it still tasted pretty fresh.
