This can have a big impact on your restaurant, for a relatively cheap price. This lets you selectively switch between different quality levels for ingredients, affecting the price to quality ratio. Grade F will make food cost 25% less to produce, but deduct -35 to quality (not bad if you have a great chef). Fresh Organic will add 20 to quality but make the food cost 10% more. Sustainably grown will increase expenses 25% but add 30 to quality.
