One of our favorite restaurants to go to in Phnom Penh is this place called Shabu Shabu. It's a Korean style soup restaurant that works like this:
You sit down with a big pot of broth (either individual or community, if you have 4 or more people) and then you watch as a conveyer belt of little tiny plates holding various ingredients passes you by. When you see something that catches your eye, you just grab it, toss it in your pot of boiling broth, wait for it to cook, and then enjoy. It's actually quite fun and quite tasty. You just pay a flat rate, and then get 90 minutes to eat as much as you want.
The last time I went there was with a large group of friends/teachers on our short vacation. We were enjoying our meal, frantically grabbing veggies, and sushi, and meats and whatnot, when we looked across the restaurant and saw this little boy. I hope it entertains you as much as it entertained us. I'm sure if everyone else in the restaurant saw this, they would be less than thrilled to throw those items in their soup. Although it does cook at boiling point, so I guess its ok :)
