OpenTable If you haven't used OpenTable yet, what are you waiting for? The restaurant reservations site is a badly kept secret. Boasting that they've facilitated over 350 million meals, OpenTable went public in 2009. The website is helpful for hassle-free advanced booking, but the location-enabled app is great for finding restaurants with available tables right now. Read reviews and book a last-minute dinner for two! OpenTable has over 20,000 restaurants to choose from. OpenTable users can earn dining dollars for keeping reservations and eating at unpopular times. Thankfully, OpenTable recognizes that being a foodie can be expensive! The free app is compatible with iPhone, iPod touch, and iPad, and requires iOS 5 or later.
