Lunch is for sandwiches, and it is our belief that the quality of a sandwich is ultimately determined by the quality of its bread. Ergo, ipso facto, by the transitive property, etc.: The best lunch spot in Phoenix is Pane Bianco, because that's where the best sandwich bread is served. Specifically, these are sandwiches served between round cuts of wood-fired focaccia that resemble a half-roasted marshmallow, or the surface of the moon. Between these doughy masterpieces are simple combinations of ingredients that pack explosive flavor. Mozzarella, basil, tomato. Provolone, sopressata, relish. And if, by some bizarre circumstance, sandwiches aren't your thing, Pane Bianco has you covered: The house-made mozzarella salad is just as juicy and fragrant as the sandwich version; the albacore tuna salad is filling without being heavy; and the pizzettes are like the younger cousin of Bianco's famous pies. Most things you eat that deliver this much joy tend to weigh you down, either with guilt or whichever combination of chemicals that causes food comas. Not so with the food at Pane Bianco. We've yet to detect any slumping in our work productivity after devouring them. And we would know: The Van Buren location, which will close soon to make way for the new location of Bianco's other restaurant Tratto, is just a few blocks away from the New Times office, and we're in there constantly.
