I have never used chops sticks, but I have always wanted to try them out.
I order chinease ALOT but have never seen one a chinese that sends chop sticks with the food, thought maybe if I was in a chineae resturant then you might have the option of using, but I have only ever been in italian or indian resturants so I'm not sure. I'm pretty sure that I could buy them somewhere, but I would need someone to show me how to use them.
