Here's an interesting article from The Chronicle that talks about the declining sales of casual dining restaurants (i.e. Chili's, Applebees, Ruby Tuesday, etc.) and about the rise of fast-casual restaurants (i.e. Panera, Qdoba, FiveGuys, etc.)
I think it hits on a good point. About a decade ago, I wouldn't think twice about eating at Chili's or Applebees. Now, I can't remember the last time I ate at one.
On the other hand, I routinely visit Qdoba and Panera, at least a couple times a month for each. I go for three reasons. Quicker. Cheaper. Better tasting food.
So, have your eating habits changed? If so, why?
