Google Squared is a Google Labs project that pulls data from various Web searches and gives you the results on a grid. It's like a Wolfram|Alpha light. The initial release left a lot to be desired, but it's starting to get more useful now.
This is the search you'd use if you're trying to find facts and figures for comparison, not a list of websites. For instance, in my neck of the woods it might be useful to compare Kansas City barbecue. Sure, you could just Google that phrase, but Google Squared provides you the information in an easy to read grid. You can see restaurant names, pictures, neighborhoods, and ratings. If you're curious about where information came from, just hover over that square.
The latest improvements increase the number of squares you can see from 30 to 120. They also worked on relevance and quality in the results. While it doesn't always provide the best results, it does learn from mistakes. In this example, I didn't need to see the style of cuisine, so I clicked on the x at the top of the column to delete it. I also added a column for price range. That said, it's still a Google Labs project, and it won't always find results for new columns.
