Sure, you can use your dining dollars at Late Night Dining, the dining centers, and places like the Minard Coffee Shop.
I also believe you can use them at Cup Of Joe and Cafe Espresso. I am not sure about the restaurants in the retail dining area in the union. I think you can use them at about anywhere that the university owns. I will look into it and see what allows you to use it etc. Ill get back to you.
