This was our second visit. Our first was an excellent intro. Service was very good and the burgers first rate - meat was cooked properly, tender and with enough char to make a pleasant crunch. The sweet potato fries were crisp on the outside and mellow within. Very much a pleasant burger experience. This second visit was disaster. The food remained as above but the service dropped like a rock. After waiting an interminable time we had to flag a passing waitress to call our to take our orders. That done, we then began another wait for our food to arrive. Enough to say it arrived well after other patrons who arrived well after us had been served. It appeared our waitress was more interested in developing her social skill than in serving the patrons . Needless to say we felt both ignored and abused. More of this and Zinburger might find it's business rapidly falling off. They just lost two who thought they had found Phoenix's burger place.
