Well, the bad news is that after eating here now I may need to relocate to Tempe, AZ.
The place is small and low budget, but I found some food favorites that I have not seen anywhere else. Tacos de buche (pork stomach?), tripitas (tripe?), lengua (tongue) aaaaaand.... sesos (brains)... plus the quesadilla de huitlacoche... well, I was not so crazy about that one, but the tacos were awesome! I even ventured to try a flan and it was very good.
