Zagat is an old, trusted friend. In the olden days, is was a deep red book, sometimes embossed with gold if it was gifted. Where the Loupe is local recommendations by someone you know and trust (hopefully), Zagat is a guide produced by the average of thousands of locals (or self procured foodies). This is perfect if you are somewhere new (that they cover) and in a pinch for a good local recommendation. The reason I am highlighting it now is that the app has improved markedly with the latest release this Summer. It seems that Google (its owner) has finally put design and development resources behind it and made it more user friendly, also expanding from 9 to 30 cities. They even changed the 30 point system to five points, presumably making easier for a wider audience to consume and contribute.
