It might take you a while to ask them all, so to make it easier Google launched a new effort to send window decals to over 100,000 local businesses in the U.S. that have been the most sought out and researched on Google.com and Google Maps. Google is calling these businesses the “Favorite Places on Google” and you’ll now start to find them in over 9,000 towns and cities, in all 50 states.

You can also explore a sample of the Favorite Places, in 20 of the largest U.S. cities, at google.com/favoriteplaces. Each window decal has a unique bar code, known as a QR codethat you can scan with any of hundreds of mobile devices — including iPhone, Android-powered phones, BlackBerry and more — to take you directly to that business’s Place Page on your mobile phone. With your mobile phone and these new decals, you can easily go up to a storefront and immediately find reviews, get a coupon if the business is offering one, or star a business as a place you want to remember for the future. Soon, you’ll be able to leave a review on the mobile page as well, just like on your desktop.
