Eat St. Forget about finding a table if you're buying lunch from a food truck. But that logistical problem hasn't curbed this trend. The Cooking Channel's "Eat St." chronicles the endeavors of mobile chefs. Kicking the concept into full drive, there's now an accompanying app. Use the location-enabled app to "discover" new street eats or to find the whereabouts of your favorites. (It's a good thing Calexico Cart stays put). When you're done chasing Wafels and Dinges, share photos and "like" your favorite places. Keep a "crave list" to help you keep tabs on the best wandering food. And use the app to watch clips of the namesake TV show while you wait for the Rickshaw Dumpling Truck to approach. The free app is compatible with iPhone, iPod touch, and iPad, and requires iOS 4.3 or later.
