OK....this may be my deciding factor as to what my next purchase of a cell phone will be. If you are not familiar with http://www.urbanspoon.com/ , you should check it out...... and if you have an iPhone you really need to check it out.
Urbanspoon on the iPhone is part "Magic 8 Ball" part slot machine. You shake your phone and it finds a good nearby restaurant for you. Keep shaking it until it comes back with something you want to try.
It is pretty amazing....I watched my son shake his iPhone letting it decide where this feeble family should eat dinner. Perfect at the end of a long day when the brain is worn out and no one wants to make a decision. The application is available (free) on the iTunes Apple Store.
