Environment Variables

Create a .env file with the following variables:

# Required for OpenAI
OPENAI_API_KEY=your_openai_api_key

# Optional LangChain settings
LANGCHAIN_API_KEY=your_langchain_api_key
LANGCHAIN_TRACING_V2=true
LANGCHAIN_PROJECT=restaurant-menu-generator

Ollama Setup (Fallback)

If you don't have an OpenAI API key, the app will fall back to using Ollama:

2. Pull the desired model (e.g., llama3.2):

   ollama pull llama3.2

Development

Adding New Cuisines

To add a new cuisine, update the Cusine enum in src/utils/utils.py:

class Cusine(Enum):
    # ... existing cuisines ...
    NewCuisine = "New Cuisine Name"

Customizing Prompts

Edit the prompt templates in src/menu_generator.py to modify the generation behavior.
