make an appointment by phone 1 days in advance. Black Pearl Restaurant is the first gourmet restaurant released by Meituan to put forward China cuisine standards, aiming at creating "China people's own gourmet list". This kind of restaurant needs to make an appointment by telephone 1 days in advance, and can only be used in the store after success. The appointment is for the convenience of stocking, which is not the same as reserving a table, and it still needs to wait in line during peak hours. "Black Pearl Restaurant" is judged by three criteria: cooking level, experience, inheritance and innovation, and is selected by many food experts anonymously.
