You cant say you have had authentic mexican outside of Mexico in Knoxville without going to Senor Tacos. My husband and I have been going weekly for over 6 years and still eperiment with new things on the menu and each time they are wonderfule. Our new favorite is the Carnitas con Chile but with Ranchero!!! Nice kick to it.
And of course there is the free salsa bar and I am talking selection not just a bowl of salsa!
