Street vendors in Bangkok, like the rest of South East Asia are every where you look. I love how anything and everything can be transported quickly and easily for sale right on the street.
I spent days just wandering the streets, trying different snacks and chatting with the sellers.
For the most part the sellers are happy to see visitors and some may even ask to pose for photos before or after trying to sell you something.
Some of the products available may surprise even the most open minded traveller, sex toys and knives being sold next to toy cars and t-shirts.
