Devoured by ravenous little swimming creatures at a fish spa in Siem Reap, Cambodia. The sensation is exquisitely ticklish because you feel their nibbling mouths taking on your dead epidermis. Though you don't noticeably see the "smoothness" in your skin after this ordeal, there's a degree of catharsis to be had. Think survival from mini-piranhas. Think micro-vanity. Think trying on a new experience... and you go back to your hotel room smug.
There's plenty of these touristy endeavors along Street no. 8 otherwise known as "Pub Street" where rows of restaurants and shops congregate.
This is the Eye in the Sky!
