The first thing I noticed when I walked in is that the building is very well designed. So for architecture I give Z Tejas a strong grade.
I'll be honest, I wasn't that excited to see this addition to the neighborhood. The Richardson's/Rokerji/Dick's Hideaway people do Southwest food about as well as it can be done and all are within an easy walk of Z. Neighborhood bar? I'll take any number of places including the Garage across the street. I'm just not sure where Z Tejas fits.
The food is exactly what you would expect, pretty good, not great. If you have friends in town from rural Washington/Nebraska/Minnesota, this will be exotic and outside their comfort zone from a flavor standpoint. Arizona people might think a little... Meh. I do like that they section out their menu to show the vegetarian listings, always a positive to make things easier on the diners.
The southwest slaw (I think that's what it's called) was one of the worst things I've ever had. It tastes like somebody took cole slaw and added all the black pepper they could find. I like pepper so I can only assume this was a mistake or designed for a consumer that has almost no sense of taste.
