Barbecue is a technology, and the price is different. Most of the technical expenses of barbecue are thousands of dollars. Learning barbecue focuses on taste, cooking is basically two important factors, and technical taste is geographical location, that is, the location of the store. More importantly, it tastes good and it's useless if it's in a bad position.

I suggest you go to a professional catering chef school to learn skills and store marketing knowledge!
