Stop in for a cup of coffee

You can get a very square meal, anywhere in VN for about $3.....LOL
When we went to Costa Rica if you went to a "locals" place to eat it was about the same price. However if you visited a restaurant the tourist ate at then you paid well for the food. Honestly we didnt care so much for that food and tried to eat where the locals did. It was way better tasting, you got more food and the cost was amazing!
