Putt Putt or Go-Kart places in Brooklyn

a few months late but
if its for kids you can try Nellie Bly Park which is just off the belt parkway.

take the bay parkway exit and follow the service road toward the cropsey exit.

the batting cages/minigolf/gokarts were gone from coney this year
ripped out for the new coney ....

john franco owns a batting cage over on 3rd ave in the 20's.
maybe they have other assorted activities. i dunno, but prolly worth a look.

and i seem to remember SOMETHING on Flatbush past kings plaza
just east(ish) of the the highway. batting cages and a golf range i think.
