This store carries several vintages of snake wine. I didn't try this time.

I tried a traditional Chinese treatment called "cupping" According to claims, it can cure everything from the common cold to respiratory diseases by having a cup placed on the skin and then withdrawing the air from it to suck the skin towards the insided of the cup. The marks last about a week, so it's not good to try right before going to the beach! Other than a few marks, it seems harmless and was about 4 USD.
