Grill House Buffet is a barbecue buffet restaurant at 70G Grand Drive in Ōrewa, on the Rodney coast north of Auckland. It mainly serves Chinese barbecue and Asian-inspired dishes, with more than a dozen hot dishes such as sweet and sour pork, char siu, Peking duck, black pepper beef, siu mai and shrimp dumplings. Premium meats include wagyu beef, lamb shoulder and Blue Diamond shrimp, and the barbecue tables are self-smoking, so diners leave without the smell of smoke. There is also a wine selection. The buffet is an all-you-can-eat barbecue at set lunch and dinner times, and is reservations only. Groups of six or more must leave credit card details, and cancellations made within 48 hours are charged 50% of the meal fee.
