How scaling works. Change a serving and calories, price, carbon and EF are scaled linearly by new ÷ default portion. Linear price scaling is an approximation — real menu prices are not strictly proportional to portion. Calories appear only where the source publishes them (— otherwise). “btl” marks 18 wines sold by the bottle (bottle price shown). Carbon = kg CO₂e per item; EF = Environmental Footprint 3.1 single score (mPt).

Calories/€ is calories divided by the scaled price, shown only where calories are published. Protein is an approximate proxy, not a measured value: a composed-dish protein density is assigned from the dish type and its main protein ingredient using public food-composition data (USDA FoodData Central and equivalent tables), then multiplied by the serving and capped so protein energy never exceeds 45% of published calories. Treat it as an order-of-magnitude guide for comparing dishes, not as a nutrition declaration.
