Last year when I was in VN, I was at a Cafe, and bought a bag of wet peanuts from a street vendor. They were very good.....But... They also made me Very sick for about 24hrs........LOL....Don't buy em from street vendors anymore....LOL...
We have a food called "Pani puri" in India, really good stuff but makes you sick when you buy it on the street. Then one day it hit me that the water is pretty much **** water. So I made some pani puri with good bottled water and never got sick. Don't drink the water.
