Let's be honest. You're not going to Taco Bell because it's super high quality. You're going because it's cheap and quick. Well - this one isn't quick... More like painfully - almost inexplicably - slow.
Update: Sitting here in the drive-thru at the 25 minute wait mark I decided, "You know what? I don't care if it's a Taco Bell. I'm logging onto Yelp and giving it a one-star for insanely slow service" only to find that I did that the last time I was here two months ago. Well. At least I'm now sure that this location is indeed horrible. :-/
