Portland's food cart scene

I have never ate from a food cart. I would personally like to go eat in one. My mom always tells me that there is a food cart by my school and that there food is pretty good. I would like to go try it out myself. I think food carts are becoming more popular because they are more convenient than the restaurants. It would be quicker to get the food and also there isn't as many people waiting for their orders. I don't have any thoughts on the food carts because i haven't got the chance to taste the food any of the food the carts make.
