This place is a bit unpredictable. Sometimes it's really busy and service becomes very slow. During lunch rush I've spent over ten minutes in the drive-through. When they are busy, quality sometimes is lower. Tacos are poorly assembled, etc.
For some food or snacks during non-rush times, they do a very good job. Fries are always fresh and perfect. Tacos are well assembled (again, not during peak times).
Employee friendliness varies greatly. Sometimes excellent, and sometimes it is clear that the person simply does not give one damn about your food or business.
