Looking for a place that sells dragonfruit
Your best bet will be in Chinatown. Most commonly I see them at Hong Kong Supermarket at 157 Hester St. between Mulberry and Elizabeth and GS Supermarket at 250 Grand Street on the corner of Chrystie, but you'll see them at fruit stands and stores all over the neighborhood. Availability and pricing can vary widely depending on the distributor, so just try your luck. If you don't find dragonfruit you'll definitely find some other exotic fruit you'll enjoy.
