iPhone apps are all about making compartmentalizing mundane daily tasks into niche-applications that actually make those tasks a bit more fun. Take, for example, the prospect of making a dinner reservation at the tapas bar down the street. First, you decide where to eat. Next you look up the restaurant on Google Maps and call the phone number. Then you actually talk to the host and work out a dinner reservation for you and your party. There really isn’t anything too fun about making a dinner reservation.
Unless you’re using the new OpenTable application on your iPhone, that is. OpenTable is an online reservation service that allows users to look up 
available tables at participating restaurants, and they’ve launched a new iPhone application that puts the power of OpenTable’s reservation system in the palm of your hand.
OpenTable for iPhone is simple to use. The application can detect your current location automatically and offer restaurant suggestions near you. Or, if you know where you want to go for dinner, you can choose a particular city (and even a specific neighborhood). You can view a list of all available tables from restaurants in your selected area, or you can choose a specific restaurant to check for available tables.
And, with a side-sliding interface, scroll-wheel menus, and a detailed list of restaurant availability (broken down by time-slots) and food-cost, OpenTable turns the mundane act of making a dinner reservation into an iPhone-based joy!
