Fast food refresh. Consumers gravitate to “better” fast food, transforming and diversifying the industry. “QSR plus” concepts with fresher menus and spanking-bright units exploit a price niche between fast food and fast casual (think Culver’s or Chick-fil-A). “Build your own” formats are springing up in more menu categories. Many quick-service eateries are adding amenities like alcohol. Others are giving up on upscaling and returning to their roots, serving simple, traditional menus at low prices.
