hey @rmjtechnologies, just did a test with the demo.
First open admin/views/themes/tastyigniter-blue/theme-config.php
Within the file, under each 'nav_menu' array item there's a 'permissions' index.
Use the value to determine which staff group privilege you need to disable in order to remove the menu item from the admin panel.
For example: to remove Kitchen, you will need to uncheck access on Admin.Menus and Admin.MenuOptions and Admin.Categories staff group privileges
