Vegan and vegetarian information cards in Khmer:

The website movetocambodia have put together a guide in Khmer for vegetarians and vegans to take to restaurants. When you print them, they will be small enough to fit in your wallet — just fold them in half and they are business card size. You can save them and have them printed and laminated at any print shop in Cambodia for $1 or $2, and can show them to the server or chef at a restaurant just to make sure they understand your request.
