I have scoured Pittsburgh for authentic, naturally leavened sourdough and nothing comes close to Five Points.
I am an artisan baker myself, focusing on Tartine-style loaves in the tradition of Chad Robertson. When I don't have time to make my own I go to Five Points.
The baguettes are from a traditional yeasted dough with a boldly baked yet thin, crackly crust and moist, open cell crumb . . . just perfect (best eaten the same or next day).
Five Points' croissants, cookies, and pastries are exemplary as well. I expect this bakery to do very well.
