Amazing organic dried mango at the sweet life. Best dried fruit I've ever had. I'd also recommend nuts about nuts, and there is also bazzini's which i've never been to. If you're up for a brooklyn foray sahadis is always excellent.
The fruit and vegetable store in the Chelsea Market (9th Ave around 15th St) has nuts in bulk and better prices than Kalustyans. They sell small and large containers of many dried fruits too, but I don't remember the fruit being available in bulk.
