🍕 Pizza Order Bot

AI‑powered pizza ordering assistant built with Streamlit and Groq’s LLaMA 3 (llama3‑70b‑8192).
The bot chats like a real server, takes complete orders, confirms delivery or pickup, summarises the bill, and can be extended with payment or POS hooks.

---

✨ Features

• Natural conversation – greets, asks clarifying questions, and confirms the order.
• Full menu handling – pizzas (sizes & toppings), sides, and drinks with prices.
• Delivery / pickup flow – collects address when required.
• Order summary – repeats the basket and final total for confirmation.
• Ultra‑low latency – powered by Groq API inferencing LLaMA 3 at blazing speed.
• Streamlit UI – runs locally or can be deployed to Streamlit Community Cloud, Hugging Face Spaces, etc.
