Kong Heng restaurant is my favourite visit every time I am at Ipoh. This changed one day wheny family arrived at the restaurant late at 3pm and many of the stalls were closing. The chicken rice stall owner welcome us and we ordered from him. Bad experience started when the chicken rice stall owner deliver the food and my wife questioning the price inconsistency. The chicken rice stall owner clarify the price and become agitated, started raising his voice and claimed that we unfairly accused him charging excessive. I have to calm him down! He keep on raising his voice on us for a minute. I did not choose to quarrel with him as I do not want to show bad example to my daughter. His chicken rice is okay but the very poor service and attitude toward customer make us stop visiting to Kong Heng again. Other stalls in the restaurant services are good by Malaysia standard. The chicken rice stall leave a very bad name to Kong Heng restaurant Ipoh. I do not think I am the first customer to get bad experience from him. I advise future customer not to question or argue with him in order to have peaceful meal.
