One of my good friends, Rama Marupilla, showed me a recent project where he used CFGrid to make a searchable, filterable restaurant locater. Have a look at http://www.nycvisit.com/restaurantweek/.
This page is a great illustration about how the power of ColdFusion 8, in the hands of a great developer, can enable powerful and relevant functionality.
Great Job Rama, thanks for sharing!
