Russian black bread - where to find outside Brighton Beach/Coney Island?

[risolatte]

I love the type of Russian black bread that is served, for example, at those Russian restaurants on the Brighton Beach boardwalk. But is there anywhere else to buy it in NYC?

Could be fresh-baked or packaged (as long as it's not too processed/artificial).

Particularly of interest would be somewhere to buy the bread farther north in Brooklyn (anywhere in the vicinity of Prospect Heights/Fort Greene/Park Slope/Carroll Gardens etcetc), or else somewhere in Manhattan.

Thanks for any ideas!!
