You must be wondering why in the world I'm giving Taco Bell four stars. I would. It's a fast food restaurant that serves high fat ground beef tacos slathered in sour cream.
What we tend to forget is that's why you come here; to get that quick fix during your lunch or dinner hour. You don't come here expecting top-notch Mexican food and if you do, well, baby steps I suppose.
Service is quick and food is what you expect. Why would I rate it any lower?
