Can you suggest a business that might work and survive? (details inside)

In the last couple of years several large (350 -700 units) apartment complexes have been put up in our town. They are located around the university and are, for the most part, filled with students. In their wisdom our city council decided that the bottom floor of these new apartment/dorms should be shops with the residential units on the upper floors. Most of these spaces are still empty. Parking in the immediate area is usually limited to non-existent. Any potential customers not residing in the building have to use the parking garage and while there are plenty of spaces it does require that an effort be made to park and walk to the potential business.
The complex I am thinking of presently has two businesses, a bar and a coffee shop. There have been a couple of clothing stores that opened and folded quickly. Both the bar and the coffee shop are making a go of it but just barely. Because of the parking situation they rely mainly on the residents for business and for the bar, where most of the residents in the complex are under age, the going is tough and I question how long they will survive. There is very little in the way of foot traffic passing by and as I mentioned parking, even short term parking is just not available. Public transportation is minimal and little utilized where I live. Most people drive to wherever they are going and most shopping and restaurants are set up to accommodate a vehicular lifestyle.
So the question, finally, is what suggestions do you have for a viable business that would either have to survive mainly by providing a service or product to a student population of 18 to 21 year olds, all of whom would be walking to it from their home or a business draw that would make it worthwhile for someone to park in a separate building and walk to the store?
