How to determine the domain model?

Question

Database design

Guys help me decide on the domain model, otherwise I can’t think of it.
My theme is a restaurant , and I need to make a small CRUD.
I came up with 2 tables
Dishes
Check
And that's it. Is it normal to do so?

Answer 1

... small CRUD - do you need these domains?

Answer 2

Didn't understand. The check seems to consist of dishes, which means there must be another table displaying the dishes in the check.
