Google revamped Zagat, rolled out a new website for the restaurant review site, released new Zagat mobile apps for iOS and Android-powered devices, and made Zagat a free service.

Restaurant review site Zagat, which was purchased by Google back in September 2011, has been revamped and relaunched. Google announced on Monday, July 29th, that a new Zagat website has been launched. Go ahead and check it out by going to zagat.com.

Google also announced that the launch of two new mobile apps accompany the launch of the new Zagat website – new Zagat mobile apps for iOS and for Android. They’re available for download for free on the App Store and on the Play Store.

• Go get Zagat for iPhone from Apple’s App Store here.
• Get Zagat for Android from Google’s Play Store here.

And I saved the best thing for last: Zagat is now free! In the past, you had to register to access Zagat reviews and ratings. You don’t have to do so anymore. You don’t have to register to use Zagat and discover the best and most notable restaurants, bars, cafes and clubs in Austin, Boston, Chicago, London, Los Angeles, New York, Philadelphia, San Francisco, Washington DC.

These are the 9 cities that are covered by Zagat at this time. Google explained that it plans on expanding Zagat to cover shopping, hotels and other places of interest in 50 U.S. and international destinations.

“These days, the challenge in deciding where to go is not about about a lack of information or user reviews, but finding accurate information and trusted opinions so you can quickly make informed decisions,” said Gannon Hall, Group Product Manager and Head of Zagat. “You can rely on Zagat’s curated lists and summary reviews to cut through the clutter so you can find the perfect spot.”
