Yeah - this is key and Mad Mex is a perfect example of this - just a clone of a national chain business model which inherently means a steady decline in quality. In the end you have what Mad Mex has been for years now: decidedly sub-par Mexican food (even by Pittsburgh standards) in a sub-par dining environment. Most of the people I know who still go to places like this have young kids, and it makes a bit of sense for them, I guess, but outside of that there really isn't any good reason to give business to these places.
