What are the benefits of on site dining?

Far too often we in marketing focus on the tangible aspects of that which we are promoting.  For example, we promote the fact that our Atlanta area retirement community offers 4 dining options serving a continental breakfast, lunch and dinner each day.  We point out that meals are served in a restaurant setting with well-appointed surroundings or we make the cliché phrase “5 star” cuisine.  However, what does on site dining mean to you?  What are the benefits of the tangible aspects we promote?  We are preparing a promotional post card to prospective Members promoting our dining options and we wish to focus not so much on the tangible but the true benefit.  Please share your experience as to the benefits of easily accessible quality dining options.
