How to call people to eat in English is more appropriate.

Hehe, in general English, you are not used to asking people to eat. This is the cultural difference. For example, foreigners are not used to using "Have you eaten?" I'm more used to talking about the weather.

Of course, a more formal statement can be that it's time for dinner, and so on. For example, there are guests coming to your house. It's more casual to go out with friends. You can use a suggested tone. Let's get something to eat. Or something to eat? Or why don't we have suppernaw?
