This location is usually pretty busy but the food is always good! Service is quick and employees are happy and nice. As for the food, it's definitely not authentic Mexican, but a brand of its own. My favorite is the sweet pork- personally I think Cafe Rio has better sweet pork, but Costa has better cilantro ranch dressing. Ask for the ranch dressing in the burrito or smother it on top- it's DELICIOUS!
