Ron,
I'm glad that you enjoyed The Real Enchilada...I was taken there by some of my colleagues when I visited our NKY office and was pleasantly suprised.
I'm struggling here in Louisville so far to find consistently good Tex-Mex / Mexican food. I have to typically scout out new places to eat either during lunch or when my wife is out of town, as my wife isn't quite as adventurous as I am, so it's my job to filter the good stuff from the not-so-good prior to taking the family there. Since I work in the East End, so much of my "field work" happens there and unfortunately, it's a sea of Moe's, Qdoba, etc. We like some of the dishes at El Caporal pretty well and several of the staff are very nice, so we usually end up there by default. I really like El Mundo, but to me, it's a somewhat different animal.
I'm hoping that someone is going to come on this thread with the end-all, be-all Tex-Mex recommendation that becomes a family institution
Until then, I patiently await.
Chris
