Sure, you're eating free-range chicken and fruits and veggies sans pesticides in your favorite upscale restaurant, but did you ever consider the working conditions "behind the kitchen door?"  Restaurant Opportunities Centers (ROC) just released its 2013 National Diners' Guide that provides information on the wage, benefits and promotion practices of the 150 most popular restaurants in America in nine major cities across the country. Now you won't have to wonder whether your server is sick or if the person preparing your food is being paid a living wage. 

ROC also is offering a free mobile iPhone app or Android app for your smartphone. Current cities include: Chicago, Detroit, Houston, Los Angeles, Miami, New Orleans, New York City, Philadelphia, San Francisco and Washington, D.C.

The app makes it easy to find nearby restaurants on a map. You can search and filter restaurants by criteria such as paid sick days, advancement opportunities and living wage. The app also provides a simple way to tweet to restaurants about their working conditions.
