I've got to go with:
Jorge's
Dos Compadres
King & I
Garcia's burritos - this place was a staple for me when I was in High School. I loved it. Every time I'm able to get back to Midland I try to stop by there. It stinks that they aren't open on weekends though.
Taco Villa - I don't think it has really expanded out beyond the Midland/Odessa area but I'm not really sure.
Luigi's
Wall Street
Where else?
