Why not just setup wifi hotspot, make the captive page the menu.

Usually the restaurant hasn’t made their own site but is paying some menus-as-a-service company to handle it for them.

E.g. https://www.meandu.com.au/

Why not hand out regular menus instead of using unnecessary technology?

Because the digital menu is cheaper. A lot cheaper. You don't have to reprint when you alter it, you can automatically move people to the right menu based on the date/time.
