Cafe Rio is a Chipotle format Mexican place - but I prefer it.
You pick whether you want burrito/quesadilla/taco/salad, then they build it for you to your spec. They even make the tortillas at a station you walk past while getting ready to order.
Generous portions, well seasoned - pretty good place to grab lunch or dinner.
I'm currently a fan of the chile beef quesadilla!
One more thing - great staff - everybody is smiling and friendly and they appear to be making their jobs fun working with each other.
