True, but OP claimed the entire category of on-demand food delivery has major problems. And 3 out of 4 of their concerns are about delivery logistics not menu standardization. Domino's turnaround shows that the food delivery model can work.

(If that sounds funny, read up on how Domino's has improved customer sat regarding their pizza quality in the past few years. It's a great case study, incl. how to do marketing when your brand is in the dumps.)
