Telegram bot for a coffee shop with menu, cart, and payment

This bot is designed as a digital assistant for a modern coffee shop. It allows customers to order coffee, desserts, or other items without queues and waiting, simply through Telegram. Everything works intuitively — the user selects items from the menu, adds them to the cart, chooses the delivery method (pickup or in-store), and confirms the order.

Main features:
- Viewing an interactive menu (items divided into categories)
- Adding items to the cart
- Viewing and editing the order
- Choosing the delivery method: in the coffee shop or pickup
- Confirming the order and sending it to the admin
- Recording in a database (SQLite) with saving order history
