As seen in Hong Kong Supermarket in Flushing, New York. Flushing is technically within the borough of Queens, but it feels like it's own little ethnic Chinatown. There are many crazy food deals to be had there (i.e. $1 Peking duck buns, 4 pork buns for $1.25, etc.).
One of the hallmarks of this community is the Hong Kong Supermarket, where you can get such delicacies as live eels, frogs, and even sea turtles.
