Where do you think Google and co. source that data from? Having an actual, searchable, up to date menu is, just for a11y and accuracy far more valuable than someone’s poorly lit, low res upload of an photo taken from the menu circa 2019, just to name one advantage. Have found data from restaurants without their own webpages on Maps utterly inaccurate, even suggesting some that have been shut down for months to where there is clear value. Then there is restaurants closing for holidays, illness, etc. and the ability to make reservations without calling. Whether these need their own over an Astro template is another topic, but having a webpage at all is incredibly valuable.

It sounds like you know everything about the internet and people's preferences, why ask?

Just a few days ago I looked up a small coffee shop on Google maps which claimed it was closed, but their own website had different opening hours showing it was open. It's a seasonal business and Google had old data. Businesses should own their own communication and not be dependent on big tech companies.

Many times information there isn’t up to date

But... why do you want to look up a coffee shop on google?

Why are you trying to put words in my mouth about visiting every coffee shops website etc? You look at possible places and choose the one(s) that appeal.

Since all coffee stores are not the same, I look at the website of the coffee shop I am considering visiting, and either I choose it or I don't.
