I found this article that in summary shows how big chains are taking market share from small restaurants.  The article focuses on tech – and the chains use of tech and how that is giving them an even greater edge over small restaurants.

Now you can fight back! At Point Of Sale Max we offer tech tools like MenuDrive that gives small restaurants a mobile menu app as well as a web based menu each offering customers a way to place orders online for pickup or delivery.
