Said mash-up in question combines location-specific restaurant and other attractions info from a company called What's Open, with Google Maps.
I guess the goal would be to get this mash-up on cell phones, and then sculpt some sort of revenue stream that would generate pay-to-call restaurant reservations and other monetizations to participating What's Open advertisers as well as carriers.
Finally, a pic of the actual mash. Sorry for the blurry but sometimes the nature of the leaks and how they are obtained are such that visually attuned, high-res jpgs just aren't available.
OK, with that said:
Hmm. Could this be a Citysearch-killer? Maybe I need to write another post on that.
