Restaurants have websites? I just use Google Places or Yelp. Not only do I get the hours of operation, a rough idea of the price, and a phone number without even clicking, I also get reviews.

Who would even think to look for a restaurant's own page?

One problem here is that these things often change and no one on Yelp will notice in a smaller community. Maybe they aren't open Monday anymore. Maybe they moved.

That's what the phone number is for. Nobody remembers to update their own websites either.

Restaurant websites often have menus and photos (of course, sometimes impossible to get to when using your phone).

Please bear in mind that places is pretty easy to stand out on, currently. The restaurants you are seeing are the ones that have hired (good) SEO people. A little bit of effort currently goes a LONG way on places (in the UK at least), so by looking for restaurants this way you'll still only be seeing a subset of them.
