Poynt is a nice piece of app as well, but Urbanspoon is slightly different.
Where Poynt is more of a YellowPages on Steroid, Urbanspoon helps you decide which restaurant should you eat out at randomly, or by any of these attributes: Suburb, Cuisine/Food Type, and Price. And it does it very quickly.
If you don't feel like having what's been suggested to you, just click Spacebar again and it will give you another suggestion. You can also see what others think about that particular restaurant.
