i LOOOOOVE Mijos!!.
While the Grapevine Mijo's location unfortunately closed, the Arlington location is still open. The food is excellent, fresh, and wonderfully prepared. I worked at Mijos for two years, when they sadly closed the doors in Grapevine. I still regularly crave the fajita nachos and fish tacos are the most amazing thing i have ever eaten. They also have the BEST vinegarette dressing I have ever tasted. The sourcream chicken enchiladas are to DIE for, and other selections like camarones, chile reillenos and steak are marvelous. Mijos is definitely one of the metroplex's greatest kept secrets. They also regularly run specials for people that hold entertainment cards for a buy one, get one meal.
In fact, they are catering my wedding next year because i KNOW they will have quality food AND service. definitely take time to check them out if you havent already. You wont be sorry!
