'The Orchard' Ave J and Coney Island avenue (somewhat near Difaras). The first real peach I have had in years. $8/lb and worth it. The proprietor will pick out the ripe ones for you.
Also of interest:
Golan dried fruit and nuts accross the street is also worth checking out.
"Essex on Coney" and other Jewish places are also good.
'The Buzz' near Golan sells electronic/household goods at good prices.
