Google is showing some users new card-style menu results for restaurants.

It would appear that this is only a test at this point, but if rolled out, this would be another instance of Google showing content to users on the search results page, making it so they don't have to click over to another website.
In this case, the result would be just as helpful to the business as a site visit, assuming it hopes to lure in customers with its menu.
As others have pointed out, it's a safe bet that Google is drawing the menu info from Allmenus.com, given that this is the source for the Menu feature on the restaurant's local result.
