Whenever you make a purchase at any restaurant, or even, anywhere, you typically receive a receipt. As a proof of purchase, and for your records, if you chose to do so.
I mocked up some layouts to get an idea of how I would lay the receipt out. I wanted to include the logo and room for the pricing and method of payment.
You can see, again I've used a complex grid, to create some spacial awareness and assure that you can easily navigate the receipt, without confusion.
You can see the final receipt design. Pretty clean design, easily nav'd. Simple. I made sure these was some reference to the in-app purchasing system.
