These are the worst quality-wise. Yes, you can write a review if something went really bad. But not having customers right there who can complain and might even get an extra or a replacement gives less incentive to keep quality up. "Specialising" in everything, pizza-burger-kebab-china, is also likely a warning sign.

This is a super good point. I didn't think about that.

IMO thats the most important point of delivered food. Just compare the process and you will instantly see the difference. In a restaurant, the waiter will openly serve you your food. You get instant feedback. And see right away if something is off. In the delivery case, you get a closed package at your door, say "Thanks" to the deliverer and close the door again. Only when the guy (who isn't responsible for the quality anyway) has left you open your package and are confronted with whatever you got. Maybe something spilled, maybe something misses, maybe something was wrong. And maybe its already cold... Whenever you use a delivery system, you take all these risks, and apart from a grumpy review, you can't do much about these... Personally, I think this is where the margin hides. Delivered food can generally have lower quality without customer complaints reaching the vendor.

I was thinking about it context of complaing to folks running the ghost kitchen vs say at a pizza hut location. I have gotten free food when they screwed up my order at pizza places, and they did care about resolving my problems.
