The raw materials for the banquet come from the Australian Thai Brothers Company. Thai Brothers was established in 1946 and has become one of Australia's largest meat mills. The products have obtained MSA rating, organic food certification, and halal food certification. The banquet uses the back breast meat as the raw material for beef rolls, and its high fat content is its most prominent feature, so it is more suitable for making crispy lamb rolls, scallion fried lamb rolls or teppanyaki. For those diners who want to try it occasionally, Xiyan is also a safe and secure ingredient with a distinctive taste, and the price of 500g bagged beef rolls is 43.9 yuan.
