I can guarantee you that unless you're an experienced professional chef yourself, restaurants make way better food than you can make at home. They make the same dishes night after night after night for as long as they're working for that restaurant. They have measurements of ingredients, cook time, how to cut everything just right, etc. baked into their muscle memory. They know every little trick and hack to bring out every little bit of flavor, which they've built through years of both experience and being taught on the job by more experienced cooks and chefs.
