Maybe a shamless plug, but I work on mobile apps at Fodor's Travel. We've been doing print travel guides for 75 years. We now have apps, in addition to books.
We're professional curators. That means every restaurant review (and shops, hotels, etc) has been written by an actual human professional who's opinion we hope you trust (we're a little more upscale than Lonely Planet, but we have our hip moments). So in a way, we're the anti-UGC. When you have crowds of people, all the ratings become a noisey 3-4 stars. Including Burger King. That's why I think Fodor's content is a good alternative. We're in the travel space, not local, but, it's a refreshing alternative.
Oh, and all our apps are FREE.
