Overall one of the best locations I've been to in Arizona. The line is never really too long or too slow. Sometimes the employees can be a bit slow or fast and some of the mistakes they make are baffling. Small examples, if the line has 5 or more people they will try to rush you through your oder as if there was a full football team in line.
Then their may be a line of 10-15 people and someone up front ordering as if they are learning to walk or ordering multiple things as they are at the register.
But the employees are nice and the location is clean. No major incidents or complaints.
