Ordered in, and the delivery man was miserable and scowling. Never even thanked me for my tip! I ordered the combo plate with sweet and sour ribs which were nothing but fat and cartilage a totally inedible. I not only spoke to the manager, but also left two messages at head office. I never got an apology or even an acknowledgement of the problem. With so many Chinese restaurants to choose from, I will never order from Mandarin again. No accountability nor quality of food or service. So disappointed
