So you needed to read a review before going to Taco Bell? That's pathetic, it's fast food and if you are old enough to check yelp surely you have slammed some sketch fast food tacos by now. Go order a twelve pack, grab a few handfuls of fire sauce, and go to town. It doesn't matter if it's clean, it doesn't matter that we don't know what they are made of; it's all part of the adventure of trashy American fast food.
