I’m currently working on a set of applications to handle the main tasks of my family’s restaurant. This is a snapshot of the client for the kitchen. It’s on a very early state, but you can mark product orders as “Done”. It uses Entity Framework and some concepts of Domain-Driven Design. It’s also using Windows 8.1 and Windows Phone 8 for the clients (the waiters will have another kind of client to request orders to the kitchen.
SignalR is needed to notify waiters when an order is ready (or even when a product is ready). I wanted to share the progress on this! 
For the moment, I think Windows 8 is a bit limiting in terms of layout. WPF is far more complete. But it doesn’t feel bad at all. I think the lack of Triggers for Styles will be a big headache, but some people are working on a MVVM-friendly way to face this using Visual States.
I also feel the asynchrony will be a major let down in a later stage of the solution, but with a bit of help, it can be done. I want to start it simple!
I hope you like it. The background is a bit lame, but I like blue hues! haha 
Hey, my picture appears in each order, but a picture of each waiter will appear in a few iterations, of course
