FYI, the grocery store a couple of doors down from Top Baguette (Bolsa just off Magnolia) had fresh rambutans today. Thought I'd mention this since it is apparently difficult to find fresh rambutans in OC. They also got their shipment of fresh durian today. They also have fresh cherimoya, pineapple, conveniently cut up durian, mangoes (little yellow manila mangoes and the big green mexican ones) and other fruits and veggies.
My friend bought the rambutans and they were 12 for $6 or so.
Agh, I forget name of the store, but if you google Top Baguette and get the address, it's like 4 or 5 doors down in the same strip mall.
