OSM has lots of POIs. OSM is more than just roads. You can add points and say "This is an italian restaurant called "La Bella Roma", it is wheelchair accessible, doesn't have wifi and is open Monday to Saturday 10am to 11pm." (which would be amenity=restaurant, cuisine=italian, name="La Bella Roma", wheelchair=yes, wifi=no, opening_hours="Mo-Sa 10:00-23:00".
OSM is trying to be more like Wikipedia, so reviews, comments and star ratings don't belong there.
Please help improve OSM by adding POIs. I'm sure you'll know something that isn't there already.
