Before the proliferation of Uber Eats, Doordash, GrubHub, etc, most of the places I've lived had 2 choices for delivered food: pizza and Chinese.
It has absolutely massively expanded the kinds of food I can get delivered living in a suburban bordering on rural area. It might be a different experience in cities where the population size made delivery reasonable for many restaurants to offer on their own.
Now if anyone solves the problem that for most cuisines ordered food is vastly inferior to freshly served meals. That would be revolutionary.
Crisp fries and pizza. Noodles perfectly Al dente and risotto that has not started to thicken.
It's far from a perfect solution, but I applaud businesses that have tried to improve the situation through packaging changes. IHOP is a stand-out here, in my experience. Their packaging is very sturdy and isolates each component in its own space. I've occasionally been surprised at how hot the food is.
