Ask HN: Best Menu/Catalog Experience

I was writing an iPad application for a client, a restaurant. App is still under development and at this point I'm not allowed to share who my client is or what we are doing specifically. But I can say it's a menu app, a simple menu app with few features.

While I was thinking about this app I thought about creating a platform like MenuPad, but cheaper & easier to use version of it. And I want people to create the app inside my web app on the web, then download & publish it, unlike MenuPad, I think. These menu/catalogs apps should be downloadable on the App Store and it also should has an optional ordering feature.

But I want to do something different, I wanted to ask peoples opinions on this subject. I'll be asking this on HackerNews and may be on few other platforms, and then update this post with those ideas.[1] I also want to ask people about how can I get the best UX? Does anyone knows a good article about menu UX? But I'm not just asking about the UX, I want ideas on every aspect of this.

Some of my ideas (I can't share the ones that I'll be coding for my client's app, I'll update this post once the app is released):

Social sharing (Facebook Like for menu items perhaps?), Optional ordering features depending on your location, Should be integrated with sales devices (like printers and other sales equipment that is used in a restaurant or a coffee shop)
