On my last visit to LA i went to an area called little Hanoi. It was like being in another country! Great place to hunt for tropical fruits. Found in some of their supermarkets fresh: jackfruit, mangosteen, durian, longan, and even some great mangos! One of the markets even had a stall next to it selling large 15 gallon sized trees of wax jambu, longans, lychees, some already with fruits, perfectly manicure, but very expen$ive.
