The demand may just go elsewhere, like “screw it, I’ll just go to the supermarket”—not sure how plausible that is in a US context specifically, but surely there’s a possible world where the majority of people just stop eating Mexican or even most street food.

We stopped eating out nearly as much during the pandemic and replaced it with higher quality groceries and prepared foods from delivery services.

I’m sure a lower-quality segment will emerge once the whole thing has time to equilibrize :) And in some places the social aspect is not insignificant. (In others you’re better off without it, true.)
