a current student here
There are places such as university stores and food centers that are overpriced for the average college student. In terms of service, bookstores, tech stores, and general consumer good store prices are generally fair for the quality of the service or product. In terms of food, such as in pubs or the dining hall, costs are a bit over-priced if you don't have a meal plan or have a small budget. The quality of food is average compared to the price they offer for it. The experience of food based on price is different for every student, but one shouldn't be discouraged in buying things from the university, as the bang for the buck is in no way unsatisfactory. It must might be a little disappointing to your wallet.
