This research is motivated by the curiosity of the ghoror influence on several forms of modern culinary business because since the end of 2019 several restaurants have gone viral for selling their food menus with the "All You Can Eat" system and some are using the sales system "Pay as much as you like to eat as much as you like" or so-called "Pay What You Want". The formulation of the problems of this research are: 1) What are the good criteria that can influence the law of buying and selling? 2) What is the effect of ghoror on the sales system with "All You Can Eat" and the sales system "Pay as much as you can eat as you like"? This paper includes qualitative research by conducting literature reviews of several sources from ulama›s books and various papers, as well as several sources from trusted websites on the internet. From this research, the authors conclude that: 1) The criteria of ghoror that can affect the law of sale are: ghoror is heavy, there is no need (hajah) syari in the contract, ghoror occurs at the main object of the contract, ghoror occurs in the mu›awadhah contract (business transactions). 2) Strong opinion on sales with the "All You Can Eat" system that this kind of ghoror is legal (light) and does not affect the contract. As for the sale with the system "Pay as Sincerely as you eat as you like" there is uncertainty about the price and the product being sold, the ghoror, in this case, is heavy, and affects the contract, therefore buying and selling using this system is prohibited by law.
