Hey pabloibanezr,
With the free version you get a fully functioning menu where you can change and edit items.
You also get all these features:
Easy restaurant menu management
Place restaurant menus anywhere with shortcodes
Built in print view with printer friendly stylesheet
RSS Feed for each menu
Multiple layouts for items
Easily activate and deactivate menu items to match your inventory
Easy CSS customizations of views
Easy HTML/PHP customizations of views for full control
Supports common responsive frameworks like Twitter Bootstrap and Foundation
Filter which categories get shown through the shortcode
There is an extended version with some extra features. Because a lot of time went into the plugin, the developers have to recoup some of their costs and charge a small fee of $15 to unlock the extra features.
It sounds like you are punishing the plugin for having premium features instead of rating it based on whether it does what it says it does.
