This message is for the poster "Hellkatte" in the EV who wanted to know where else she can get Boloniya bread, the intensely buttery, almost cheesy tasting, brioch-like but moist bread made by the St.Honore bakery based in New Jersey:
I've only gotten it from the JAS mart on B'way and 110.
They run out fairly quickly. Now I know there are other JAS marts in the city, probably closer to your neighborhood. Perhaps you'll have good luck there?
