Tony and Cindy Waldrop have been serving Tex-Mex to loyal customers since 1979. This location is expansive (though you wouldn't think so from the outside) with two floors and a patio. The latter is a favorite of the weekend crowd enamored with the 60-ounce margarita. But the name says it all. When at the colorfully decorated Enchilada's, order its namesake, especially on Wednesdays, when you can enjoy the Original Enchilada Dinner for only $4.79. Lunch combos don't break the 10-spot mark. With the exception of some of the fajita specials for two, most menu items aren't priced above $15. All of that, combined with the fact that readers of the Dallas Observer voted the restaurant's wait staff the best in Dallas in the newspaper's 2010 Best of Dallas issue, make it one of Big D's most stable Tex-Mex staples.
