## Overview

Grand Palace is a Flask-based food preordering and kitchen-management system. Customers authenticate, browse the menu, maintain a cart, submit orders and track kitchen status; kitchen staff manage requests, order states, menu availability and operational settings. The implementation is concentrated in app.py, with HTML views under templates/. The README documents payment, OAuth, and media-management capabilities, but the excerpts do not show all their implementation details; those links are identified as documented rather than inferred from unseen code.

Main entry points: [`app.py`](https://github.com/charan30301/food/blob/main/app.py) (Flask routes), [`templates/menu.html`](https://github.com/charan30301/food/blob/main/templates/menu.html) (Menu view), [`templates/cart.html`](https://github.com/charan30301/food/blob/main/templates/cart.html) (Cart view), [`templates/admin_dashboard.html`](https://github.com/charan30301/food/blob/main/templates/admin_dashboard.html) (Admin dashboard)
