The waiting time depends on the passenger flow of Haidilao and your queue number. Generally speaking, if it is during off-peak hours, the waiting time may be relatively short, about half an hour to an hour. But if it is during the peak meal period or holidays, the waiting time may be longer, and it may take two hours or even longer. If you make an appointment in advance or get the number, the waiting time may be shortened. I suggest you pay attention to the official account of Haidilao official website or WeChat to know the latest queuing situation and estimated waiting time.
