Other than the fact that it is not in a diner shaped building- there isn't much difference between 5 & Diner Delux and the regular 5 & Diner.
The menus are pretty much the same with standard diner fare. The big difference is supposed to be that they prep there own food, but I couldn't really feel the extra love in my bacon cheeseburger.
I guess the biggest dissapointment was the fact that my chocolate shake was made with vanilla icecream and chocolate syrup. This produces the same flavor as a fast food shake and the steep price of $4.49. A chocolate shakemade with chocolate ice cream is just more authentic and really what this pregnant lady was craving at the time.
