For over 80 years, Chain Store Guide has been the leading provider of comprehensive and definitive retail and foodservice intelligence to businesses around the world. As retail channels and industries developed, Chain Store Guide was there to define the markets. Today, CSG continues to be a primary source of information that business professionals rely on for timely and accurate data on the evolving retail and foodservice industries. CSG data is compiled by our staff of editors and research professionals. While some companies simply compile data from sources such as the Yellow Pages, Chain Store Guide researches every company profiled. Our staff contacts these companies to verify information and ensure data is accurate and current. The result is better data -- truly useful data you can count on to build your business.
