In all honesty I consider Open Table to be one of the most convenient services ever created. I don't have to call restaurants multiple restaurants when I'm trying to make a booking and I can easily discover new eateries or places I've never visited. Fortunately, Open Table's app takes that convenience and puts it on your phone. You can search by multiple filters (type of food, price range, etc.) and you can read menus and user reviews. What's more, the broad coverage in the United States and abroad makes it great for traveling.
