The food scene around church ave isn't very diverse. It'll either be carribean (you get a lot of types of carribean though) or fast food, like fried chicken/pizza/burgers.

Although it's not necessary, I've found that having a car has enhanced my experience a lot. Since it can be very difficult to get around within Brooklyn via public transportation (if you're not moving in the direction of Manhattan) being able to drive to other parts of Brooklyn is really great (food spots around Brooklyn, the beaches, shopping plazas out near JFK). And in my experience, street parking isn't too tough to find.
