Once I watched a woman berate half the staff because she "didn't like people touching her food". She was crazy, rude and unreasonable as she tried to get her 3 bags of food for free. You would never know it based on how the staff reacted, they were so calm and professional and never once got pulled into her drama.
The salsa bar could be cleaner but it is always well stocked. Salsa is messy.
My standard order is one chicken leg and a bowl of the tortilla soup. I love this soup, they don't skimp on ingredients. As far as fast food goes it is great and I would return many times.
