We order from China Chef all the time. We do, however, pick up our order, but it doesn't matter how many meals we order at one time, they have never made a mistake. Our order has always been complete and correct.
This must be some of the rudest people I have ever met. Their delivery service is terrible. Takes well over an hour for delivery and sometimes they don't even make it. They are abrupt over the phone and do not answer your questions. Do not order from this restaurant unless you wish to be aggravated.
