Build me a simple restaurant system app for a school assignment, with a clean interface and basic working features for managing restaurant tasks.

I want it to feel like a small real app a restaurant could use, so someone can view menu items, add or update food details, and manage orders in a straightforward way. Keep it easy to use, with clear screens and simple navigation. If it makes sense, include a way to see customer or order information and basic status updates too.

Use whatever project structure fits best for a C# restaurant system, and make the app polished enough to demo. Please keep the code organized and readable, and if you need to check anything, look up current docs online. I mainly want a complete working version I can open, run, and show for my assignment.
