Scale does matter, though. The little thing that elevates restaurant (and especially "street food", for some reason) is usually garnishes. Small amounts of fresh ingredients are a big pain for home cooking because they require disproportionately more effort. Whereas the things that do do better at home tend to be long slow dishes that you don't get in restaurants because of the lead time.

It's certainly very easy to do better than chain fast food. And my opinion of a certain local cafe was diminished once I got a Costco card and recognized the muffins.
