Karczma Brooklyn
Karczma, on Greenpoint Avenue, just west of Manhattan Ave. Upscale peasant food, if that is not a contradiction in terms.
Any bakery along Mahnattan Avenue will fill you babka needs, although I am partial to Rzszowska, or something like that, on Manhattan and Java St.
I'm also fond of the Polam Meat Market, again on Manhattan Ave between Java and India, but I suspect any meat market/deli has the same quality offerings.
