If you have professional knowledge in this field, or you are an experienced barbecue chef, it is even better. The area of the shop doesn't need to be large, but it can't be too biased. There are not many kinds of roasted meat, but 7-8 kinds (marinated products) are good at it, such as roast goose, roast duck, sparerib with honey sauce, white-cut chicken, brine chicken, fried chicken with soy sauce, large intestine with brine and pig.
There are basically two development routes for roasted meat fast food restaurants:
First, develop into chain fast food companies, such as Datang Roast Goose Group in Guangzhou; Second, develop into Chinese-style old shops and famous shops, such as Hong Kong Yongji Restaurant, which is well-known at home and abroad.
For details, please consult some professional planning and training institutions for free. Here, I would like to introduce a professional planning and management company in Hong Kong: Hong Kong Tang Pin Catering Management Co., Ltd. They are very experienced and helped to plan our Ningfuji Roast Goose Restaurant in Dongguan. They have a website, which can be found in Baidu.
