Simply Frustrating

I was really excited when I found this plugin. Unfortunately the plugin is so poorly designed and documented that it turned into a frustrating experience. They could have provided better instructions how to use and edit the menu. What’s the point of using a plug-in where features that a restaurant menu has to have are locked out? Why not giving a 14 day full feature trial? This plugin claims to be compatible up to wordpress 3.7.1 but it’s not working on my end (running 3.7.1)
I was planning to purchase this plugin after inital testing, but honestly I feel a good old pdf will be my choice until I find a better plug-in.
