Legendary Margs. Tasty Mexican. Good people. After many life-changing adventures through Mexico, these are the founding principles which three guys from the Gulf Coast opened the doors of the Rio in 1986. And from that moment, it’s every single person who’s stepped through them that’s helped grow this tradition. It’s in the air. On every plate of food. It builds with each conversation. What started over 30 years ago, are the times we still crave today.
