Why does Caz rub you the wrong way? OTB rubs me the wrong way, too, but it's because of the bland, nasty crap for food and the commercials with the horrible fake accents and/or the ones saying OTB is better than your typical Mexican restaurant because all the servers speak great English.
If OTB is considered "decent" Tex-Mex, Tex-Mex must suck in general. JMO.
Baja Fresh is good...they all shut down at once in KC a couple years ago.
Better than Rubio's, though?
