Until recently I have been a long time patron of what may have been the finest Chinese eating establishment in Arizona. There were many memories made here. I moved away several years ago which made it difficult to get back to one of my all time favorite restaurants. Recently between appointments I found myself at lunch time both hungry and near this landmark. I was unaware of the ownership change until I walked in and was not greeted by familiar or friendly service. Since I was on limited time I ordered from the lunch menu expecting the the same service as I had been accustomed. Wrong. The order was taken in reasonable time but the food arrived luke warm almost 35 minutes later as I was preparing to leave. The lunch special wasn't very special and bordered on disgusting. Running late for my appointment, I had to track down staff so that I could get a guest check and pay my bill. I can say that both service and food quality were consistent: SUB PAR. It is unlikely I will return.
