Worst Burger I've had in a long time. I ordered med, got well done, cold and cheese was not melted. Never saw a manager and server could not keep up. Never checked to see how our food was. Food took 30 minutes for two sandwiches. My co-workers sandwich was cold as well. This was the latest in a string of disappointments for this place. Only thing keeping the doors open is the army base across the street.

pick from the following. 1. negative; 2. positive;
