La Barceloneta Specialty

You might smell Baluard Barceloneta before you see it—the sour smell of the bread (all of which is made from homemade sourdough starters) is known to waft through the neighborhood. The bakery itself is run by Anna Bellsolà, a fourth generation baker who has become famous for her airy, just-chewy-enough baguettes and Italian loaves. One of the best things about the place is its exceptionally local feel; bread is blessedly inexpensive and you're likely to wait in line next to hungry kids and elderly shoppers alike. There's a glass partition separating the customers from the back-of-house, so you can see the bakers working, moving loaves in and out of the wood-fired stone oven.
