It's such an obvious feature it's hard to believe it wasn't already there, but the latest update for Amazon's Echo lets it pull up Yelp recommendations for restaurants and other local businesses. Just ask about info on where to get Chinese food or pizza delivery, and it will send the Yelp-powered results to the Echo app on your phone or tablet. For it to work you'll need to have your local address set up in the Echo app, but that's it. Amazon says more local search results are coming soon, but for now you should also know it can help you easily stock up on Halloween candy. Just ask the speaker to "order Halloween candy" or "order Halloween chocolate" and it will -- provided you have voice purchasing enabled (read: disable voice purchasing before your kids find out about this feature).
