According to their type, the food items are allocated into six categories: Bev - Beverages and fizzy drinks, Break - Food items served at breakfast, Coffee - Coffee-based drinks, Meat - Meat-based items (not served breakfast), Shakes - Shakes and smoothies, Sides - Fries and sides. A classification tree was fitted to the data with the purpose of classifying the food items using the information on their nutritional values. Below a visual representation and the associated output (note that the node numbering of the tree does not match the node numbering in the output).
