You can survive, and even become a little plump, on dining hall meals. There is always plenty of food, but the food itself it not always so tasty. There are some people who are tremendously fond of the dining hall and sing its praises, but most students find themselves looking for other options pretty quickly. The food courts are a good place to use your points, and students often find themselves choosing fewer meals in favor of points.
After some time, students figure out which dining halls prepare which meals the best and move between them to satisfy their cravings. One of the major motivations to move off campus is the ability to escape the dining hall food. The dining hall experience gives you a new appreciation for cooking, and most students are happy to break away from the poor quality, tasteless meals that the dining plan offers.
