We have enjoyed what we thought was one of the better cheeseburger plates in the valley... at a DIFFERENT Coco's than this one. Five stars at the Coco's on Bell Rd in Peoria. Zero stars at the Coco's in Sun City Grand. Service was terrible (very slow and they gave us both the wrong side dish. ) We pointed it out and they said, "Oops...Sorry about that." AND WALKED OFF. The cheeseburger was so overcooked that the cheese was crunchy and black. Slimy lettuce. Empty water and soda glasses stayed that way. We joked that the entire staff had gone on break at the same time. It wasn't busy at all. Word must be getting around. We vowed to NEVER return. Terrible food. Worse service. Why would we do that to ourselves again?
