Restaurants don't even need a dedicated take-out ordering section since delivery apps cover that too.
I rarely see Squarespace or Wix.
They already do.
e.g. our landscaper's website is something like:
bobslandscaping.landscaper.com
It handles the invoices and hosts his basic contact information etc. Sounds like a great business to be in to be the hosting company for this.
Where I live in my part of Europe, most small restaurants, cafes, bakeries etc. only use a Facebook page and their Google maps entry to share their menu, phone number and interact with the customer base. They have no use to spend time and money owning and maintain a website, plus the advantage of even grandmas knowing how to update a Facebook page versus stuff like shopify or squarespace.
And restaurants very commonly have events, either private events closing the place for other guests, or public events with a lot of people wanting to book. In these cases an online platform is even more useful. Then you remove a whole lot of calls.
