Well I'm in kind of a Hurry and can't read all 6 pages but I didn't see mine listed. Don't get me wrong I like most of the places listed here with. They all have things that make them good IMO. However for the best overall Tex-Mex you need to try out El Paseo in Lake Worth. Do not compare it to the same El Paseo in Keller, I've heard the food just isn't as good (I blame it on the chefs).
Anyway my all time Favorite dish is the Polo Ranchero and I cut it up and eat it like a Fajita. Now if don't like it that spicy then you need to order the Fajitas, they are the best I've ever had anywhere. I also like to recommend their Botano Platter which is a sampler plate but damn it just gives you a taste of how good everthing is. Oh and their Margarita's rock as well
