For buffet, of course Amazon~~The prices of Amazon are different in each place, but they are all about the same. The one on the top floor of Yongle Appliances on Xueqian Street seems to be 59 at noon and 79 at night. The one on Wuai North Road is cheaper, it seems to be more than 40 at noon and more than 60 at night (in fact, the dishes at noon and at night are similar, but there are more people eating at night, so it is more expensive). There are also two Amazons in Oriental Paris Plaza opposite Sanfeng Restaurant on Chongning Road, also 59 and 79. If you want to eat a self-service hot pot, there is the Arc de Triomphe on Oufeng Street, and there is also a self-service hot pot for one person in Chong'an Temple. If you want to eat a self-service barbecue, you can go to Oufeng Street, there is a square next to the Walmart supermarket with many barbecues, such as Brazilian barbecue and Baidu barbecue~~
