Kiosk GUI layout

I need to develop a GUI for a self-service kiosk. The kiosk will take food orders (i.e pizza,开发者_StackOverflow burgers, salads) and provide the ability to pay using a credit card. Can anyone suggest the best GUI layout or approach? I want to make it intuitive and simple. I want to minimize the number of button clicks. If you can provide examples, that would be great.Thanks for your help.

A couple of ones i prefer have the fields for the delivery details (address & dynamically generated order listing) on the right side as a small strip, the product category you're currently browsing to the left and category navigation tabs either at the top or as a thin strip in the outermost left position. No need to re-invent the wheel. That way the user can browse, already specify the address details and always keep track of the already added order positions, modify item count and keep track of the resulting costs.
