OpenTable is the perfect app for those that like to go out to eat.  By selecting a date, time, and party size, you can make reservations at pretty much any restaurant that takes them.  By inputing your selections, OpenTable will present you with your preferred number of options, each with a distance from you, price range, and cuisine category.  Once you pick out a resteraunt, you can select a time slot from the available options and make a reservation.  If you create a free account, that’s all you have to do; if not, you must also type in your name and number.

If you are unsure of a restaurant, you can read a blurb about it, get info on parking, read extensive user reviews and ratings (even has noise level rating), and look at a full menu.  The easy-to-use user interface also allows you to search by location or restaurant name.  If you sign up for an account, you can gain reward points netting you coupons.  OpenTable is a great app that lets you make reservations without any hassle.  This is a must download for those that frequently partake in fine dining.
