But within the same example its not as good as if you ate the exact same meal freshly served - things won't be as hot and certain textures will be lost in delivery (eg crispy things going soggy)

You mentioned a chef which is less specific but I generally consider restaurant food less healthy than what I'd cook for myself due to differing incentives which is another dimension for convenience
