I think if you are half capable you should just adopt the project and do it for free.
I have a web app that is a html document with an [edit] button at the end. It points at edit.html which has a textarea, a password field and a submit button. (Below is a list of links to all pages in the folder starting with index-) The textarea shows the middle chunk of the html document. You edit it, fill out the password (the browser will do it) and press the save button. It posts to save.php which constructs a new index.html and save a copy as index-2026-03-18.html The link to the copy shows up on edit.html The edit link there points to edit.html?file=index-2026-03-18.html if you save it that will become the new index.html (it refuses to edit anything that isn't "index-\d\d\d\d-\d\d-\d\d\.html")
If each menu entry is: `<tr><td>Beer</td><td>$3.50</td></tr>` They can just edit, delete or copy and paste it. Simply: `<br>Beer $3.50` Would work just as well. If they screw up they can put back an older version.
Put your phone number on the edit page. Write some html tags on a napkin. `<br> <b> <i> <h3> <img> <a>`
They want more pages? make the /about folder drop index edit and save.php into it, remind them to make a link to it on the front page and they will figure it out.
Firstly, I think you missed that they are small business-owners and simply do not have the time to manage this. Even if I volunteered to do charity work for a local business, they would still need to spend the time to get onto the old developer to transfer domain access, host access, billing info, etc.
Secondly, I no longer work near there and haven't gone to that cafe in about 5 years. I keep up with old colleagues who say the cafe is doing well, but now if I had taken on that work now I'm their contact.
Lastly, this is all ignoring the maintenance cost. What version of PHP? What version of Apache/NGINX/Traefik? Any security vulnerability in Ubuntu in the past half decade? Now we have to play the security cat & mouse game.
At the end of the day, while I don't want to go to Instagram/Facebook to find menus/opening hours, the truth is that it is significantly easier for the average person to just make a social media post.

Why? A website is a standard business expense. Should their accountant work for free also? And their waiters and kitchen staff?
