There's a real dearth of fast-food style tacos in this town. Not "authentic" taco-truck style/gas station tacos, the guilty pleasure fast food style tacos...but other than Jack in the Box and Taco Bell (eight locations locally) there's nothing to really sate those cravings.
Pepe's when it executes well works, but it rarely executes well and more often than not has been a consistent disappointment. Taco Bueno tends to open stores and then closes them within five years, while Del Taco tried to make a big comeback in Texas in the early 2010s but closed their stores within a few years, and never here. (The comeback version, that is.)
