Keller's Cactus Jack's (Dallas, Texas)

What luck! Loopnet has a picture of it as Cactus Jack's (the original exterior).
4341 Lemmon Avenue in Dallas was originally built as Del Taco, which operated from 1979 to 1981 (I believe Del Taco pulled out of Dallas first, then Houston...it's a long story), and then became Cactus Jack's, also known as Keller's Cactus Jack's, a local hamburger restaurant that also served beer, hot dogs, and other types of sandwiches including grilled cheese. In 2010 they closed after 28 years to be leased to Carl's Jr. when CKE Restaurants an ambitious plan to add 170 Carl's Jr. restaurants to Texas (that was a lofty number, I don't think they got anywhere close to that and all but a small handful have closed), which opened in late 2010. By spring 2014 it was already gone and replaced with a Taco Bell.

I'm not sure what exactly was the difference between "Cactus Jack's" and "Keller's Cactus Jack's", which tax records show. As this was still owned by Keller prior to 1990, I assume it was differentiate from independent establishments with similar names.
