that's why you get restaurants whose menu is only available as a PDF, a deeply mobile-hostile format, when just putting it on the front page would actually be easier and work better for the user.

IMHO that's still better than making it an SPA, because the former at least can be easily downloaded and viewed locally. Another example I've seen is a recent redesign of a public transit site, where a simple HTML form and directory of PDFs (literally --- it was just the webserver's directory listing) for finding bus schedules was turned into an SPA that took a disturbingly long time to load and was filled with, as the sibling comment puts it, "flashy, user-hostile crap". The old design was unchanged since at least 1999, if not slightly before.

A local restaurant had their menu redone in React! Not just React, but React done badly. Click on "Lunch Menu", say, and literally nothing changes for 30 seconds. Then the new page appears. I took a while to realise it wasn't completely broken. God knows how much they paid for it. It's awful.

Edit: I should add, this reactivity serves no purpose. It's a sit down restaurant. You can't order electronically.
