Glass Digital shared a screen shot on Twitter of Google showing extra local review data from the popular UK paper, The Guardian. In fact, there is a special Guardian logo/icon near the review for the "top ten" in a category.
Here is his screen shot:
You can see the icon coming up twice, one for "top 10 budget eats" and the other for "top 10 craft beer pubs." The Guardian has content that matches these types of searches, so I guess they partnered up with Google around this.
This may be old news, as I don't often search for restaurants on Google, espesially ones in the UK, but let me know if you've seen these before.
