I mean as far as fast food goes, it's better than most, but you still walk away feeling really icky. Also, the staff seems to get orders wrong frequently, check out the quarter 4 reviews of 2016 on Yelp.
I don't think this place deserves a straight up negative rating per se, but it's hard to find a fast food restaurant that enforces high standards, other than like.... In N Out. But we won't go there, lest a "In n Out versus Carl's Jr" debate erupts on Yelp. Not that it hasn't happened before...
