Foodie the iPhone app debuted four months ago (the brainchild of Chicago food writer Ari Bendersky and his business partner and digital strategist, Matt Marcus), and it was a good idea from the start -- a way for diners to book tables at some of the city's most popular restaurants AND get daily specials and little dining perks (a free dessert here, a discounted prix fixe there) exclusive to Foodie users.

Good turned to great this week, as Foodie has launched a Web site, making those 'exclusive' deals available free to the masses now, not just iPhone users (the app costs $1.99). More than 60 restaurants (Graham Elliot, Spiaggia, Lula Café, and so on) offer deals through Foodie.

Speaking of iPhone apps, Vienna Beef has gone viral, too, with a Vienna beef hot dog locator app. Users can zero in on the closest purveyors in their zip code. It gets better: They also can play hot dog cop, flagging hot dog stands that are "No Ketchup" violators, a release states.

The Vienna iphone app is free and available at itunes.com/appstore or here.
