While there are many Mexican restaurants in the O'Fallon and surrounding communities, none really match the history and consistency of this location.  The owner also owns Mario Cafe, not far away.  It is also a highly rated restaurant that can't be compared to other restaurants with its 4.9 Star rating.

It is a featured member of St. Louis Restaurant Reviews' online ordering system, known as eOrderSTL, which is owned and managed by St. Louis Media, LLC.  We are selective about who we put on the system, as they have to have a history of high customer satisfaction, which is demonstrated by their online ratings and reviews.

When we visited the two locations, it was obvious that customer satisfaction is at the top of the list of priorities.  We are excited to be working with this restaurant owner, not because he is a new member of eOrderSTL, but because it is hard to find a restaurant owner who is actually engaged in their business currently, as the sales and inflation have destroyed a significant amount of hope and ambition, not with this group.

Additionally, we carefully analyze our members, as we have learned from previous restaurant owners that we need to verify their representations.  This is a first-class operation where the owner takes compliance and customer satisfaction seriously.
