In the food and beverage industry, a key differentiator is restaurants' ability to offer a highly customizable menu.

We’ll explore the relationships between products, modifiers, and modifier groups and demonstrate how to implement this design using SQLAlchemy and SQLModel, two powerful Python libraries for database management.
