I'll preface this by saying I'm from Texas and I'm comparing this to some of the great Tex Mex that we have back home. This place is okay. It's not great and I probably wouldn't go out of my way to go back.
The chips didn't appear to be from a bag and not made at the restaurant. If they were made in the restaurant they weren't very fresh. They weren't bad, but I've had better. The salsa was decent.
I ordered the lunch combo fajitas and they were okay as well. The tortillas were store bought and the rice and beans were pretty much flavorless. The meat and vegetables were not bad themselves.
Overall it's okay. I don't know how it compares to other Tex Mex in the area as I haven't tried it yet. I will say that the people are super friendly and if you are craving Tex Mex this might work well for you. My Tex Mex standards are pretty high.
