Hello,

Go to Pages > Add New to create a new page for each restaurant.
Add the restaurant’s name as the page title and any additional information you want to include (e.g., description, location, contact information).

In your WordPress dashboard, go to Appearance > Menus.
Create a new custom menu and add links to each restaurant page you created.

The Screenshot that you sent me can import it via the theme library.
