From what I've observed in different parts of the world, small restaurants, hair salons, beauty salons, boutiques, etc. all go straight to Facebook/Instagram. Opening hours and driving directions are already there, menus/offers are in the gallery - together with pictures of the meals or whatever they are selling. Contact forms are replaced with a WhatsApp number. Testimonials are the customers comments. If there are negative ones, either respond for bonus points or just outright delete them.

Restaurants don't even need a dedicated take-out ordering section since delivery apps cover that too.

I rarely see Squarespace or Wix.
