Brooklyn Botanical Garden, more or less adjacent to Prospect Park (which was done by the same F. L. Olmstead who did Central Park). And there is a zoo in Brooklyn: the Coney Island Aquarium, which has a station on the Brighton Beach and Culver lines (West 8th Street, Q and F) one station away from the Stillwell Avenue double-ended 'terminal'.
Remember, Brooklyn has enough street grids for several cities. There's 8th street (one grid), North 8th Street and South 8th Street (in Williamsburg), East 8th Street and West 8th Street (between Prospect Park and Coney Island/Lower NY Harbor), Bay 8th Street (in Bath Beach), Brighton 8th Street (in Brighton Beach, part of Coney Island), Brighton 8th Place and Brighton 8th Lane (pedestrian-only alleys near Brighton 8th Street), Paerdegat 8th Street (off Paerdegat Basin) and Flatlands 8th Street (in Canarsie, not Flatlands, off the basin called Fresh Creek).
There's also an 8th Avenue in Brooklyn.
During the Levittown era, a developer created a community a little past the city line to lure people from Brooklyn. It is called Lynbrook.
There actually is an 8th Street on Staten Island, too, in New Dorp.
Queens has a very short 8th Street, east/south of Hallet's point.
Manhattan, of course, has East 8th Street and West 8th Street.
The Bronx does NOT have an 8th Street. In the days before the five boroughs were unified into one city, the Bronx was part of Manhattan for a while. There was an attempt to align the street grids of Manhattan Island and the mainland part of Manhattan, which has left a massive scar on the Bronx grid.
