Scenario:
It's 10PM on a weeknight and you feel like having a Burrito. Where do you go? Taco Bell, that's where!
This Taco Bell has been around for a very long time, I remember going to this place since I was in grade school. The restaurant itself hasn't changed very much, the interior has stayed the same since (I presume) since it opened. Regardless of the interior; where it counts it behind the counter and what's being created there. On a general scale, yes Taco Bell isn't the greatest, but for fast food it's pretty damn good. They have a decent selection of Texmex cuisine to fulfill your cravings.
The service has been pretty good (at least in my experience). But let's be honest you're not coming here for 5* service. Other than that my only recommendation would be for this place to renovate; it's long over due.
