Friends who have eaten Haidilao know that if you don't make an appointment in advance, you can't finish eating hot pot for dinner for two hours. But if you are a member of the Black Sea, no matter when you go and how long you wait in line, just tell the waiter "I am a member of the Black Sea" at the door, and the other party will arrange the nearest number for you immediately. Secondly, when Black Sea members dine, the exclusive member logo will also be placed on the dining table.
