/ck/ - Food & Cooking

I don't know where else to ask this but how do chefs adapt normal recipes for restaurants?
I assume most restaurants have to cut down on the cooking time so is there a set procedure to convert a recipe for home cooking to restaurant?
What do they usually cook in preparation and what do they cook when the meal is ordered? Are some recipes necessarily just cooked in advance and reheated on the day for example stews and braises?
