This guide walks through the minimum steps to get a working food menu on your Joomla site: create a category, add meals to it, then display everything on a page using a Joomla menu item.
Categories group related meals together on the frontend. Go to FW Food Menu → Categories in the Joomla administrator and click New.
Save the category before moving on.
Go to FW Food Menu → Menu Items and click New. Fill in the standard fields for each meal or drink you want to list.

Repeat for each item. Once you have multiple items in a category, you can drag rows to reorder them on this screen.
Additional fields such as images, nutritional information, allergens, and price options become available when the corresponding plugins are installed and enabled.
FW Food Menu uses standard Joomla menu items to display its frontend views. Go to Menus → [your menu] → Add New Menu Item and click Select next to the Menu Item Type field.

Choose Food Menu → Food Menu from the list. This displays the full menu with all published categories and their items. Give the menu item a title, assign it to the appropriate menu position, set its status to Published, and save.
Before previewing the frontend, confirm a few global options under FW Food Menu → Settings → General:

Navigate to the page linked to your new menu item to confirm categories and meals appear correctly. If nothing shows, verify that both the category and its items are published, and that a theme is selected in Settings.
