New York City MenuPages.com + Google Maps - Will Schenk had a thought: "...I live in New York City and I eat out a lot. I end up going to the same places a lot of the time, places in familar haunts or places I hear about from other people. But it often happens that I'm little for something in a neighborhood and there no good way of doing proximity exploring. I'm always scrolling through citysearch for example trying to find a sushi-no-maybe-indian place in some neighborhood I'm not familiar with. So I decided to take my favorite site, menupages.com, which has the menus of these places online, and plug it into google maps." Check out the mashup he created here.
