Fried spider is a delicacy in Cambodia. This specialty snack is a popular attraction for tourists. The spiders are bred in holes in the ground in villages north of Skuon, or foraged for in nearby forestland, and fried in oil. The spiders are a species of tarantula called "a-ping" in Khmer, and are about the size of a human palm. At nicer restaurants the cost is $4.25 for 4 spiders.
Silkworm aka Beondegi
Beondegi, boiled silkworms, is a popular snack in Korea. They are served warm in a giant pot and soaked in boiling water, where the vendor will spoon a handful of them into a cup for you. It's only $3 for a healthy-sized portion that's definitely enough to make you feel nauseous.
