We're Back! Grand Re-Opening at 825 S Western Ave in Chicago!

After six years of absence, Trans-O-Mex is re-opening its original location at 825 S. Western Ave in Chicago. This location first opened its doors for business in May 1980, operating successfully, until there was a need for a bigger location and went on to build a larger and more modern shop in Cicero, Illinois. Today, thanks to the support of our customers and feeling a need to be closer to our clientele in Chicago, we are proudly re-opening our original location. Starting February 2010, Trans-O-Mex will be open for business at both locations to serve you better: 825 S Western Ave in Chicago & 5000 W. Cermak Road in Cicero.
