ArvindRamakrishnan78907/Restaurant-Billing-and-Management-System — reverse-engineered prompt

Build me a simple restaurant billing and management web app from this starter project. I want two sides, one for admin staff and one for customers. Admin should be able to add, edit, and remove menu items, manage table status, and see and update incoming orders. Customers should be able to sign up or log in, browse the menu, add items to an order, place it, and check their billing or order history later.

Please make it feel like a real usable app, not just a demo counter page. Keep the interface clean, mobile friendly, and easy to understand. Use the basic web setup that is already here, and if it makes sense, turn it into the planned version with a small backend and database so orders, menus, tables, and billing history are actually saved. Seed it with a few sample menu items and tables so it works right away.

If anything is unclear, look up current docs online and fill in the gaps with sensible defaults.
