自助餐 buffet / self-service meal A buffet usually has a very large range to choose from, much like a restaurant. A self service meal is small, has rice and a few things to choose from. More like a company canteen.

高档的通常是“buffet”

我只知道我们去吃的自助餐是这样的：每人付指定的钱进入就餐区，自己任意取食食物，但避免浪费，有些是直接可以吃的，有些需要自己把它们煮熟；不可打包。

buffet是中国的自助餐~~这是我的外国朋友的理解
