I nearly always cook at home. When I go out to eat, it’s to get something that I can’t make myself, or it would be too expensive/ time consuming to get all the ingredients and make it myself. That usually means stuff like sushi and ethnic food.
My favorite dish like that is Vietnamese pork chops. There are a couple different things in this dish where it would be a huge pain to make it at home. The pork chop is marinaded in fish sauce and grilled perfectly. It comes with shredded pork skin, a little pork/ egg/ vermecelli noodle cake, rice, sunny side upp egg, pickled radish and carrots, salad, and fish sauce/ lime juice dipping sauce. But if you get it at the right restaurant, all that stuff is like $8.
