New York Google Maps Bar site
Whilst the execution of this idea is pretty average the idea and application of Google Maps in this fashion is really interesting. Any bar that's signed up to a certain promotion could be pinpointed with a link to their website, videos of their cocktail mixing, images of their clientelle and a cocktail list. It's a great way of taking a promotion to the trade and engaging increasingly savvy consumers.
This site was publicised on Coolhunting a few weeks ago. Back then their was no advertising. 2 weeks later Cabana Cacacha have used the site for advertising.
