Here's a unique one that has been in the headlines recently: Kogi BBQ!
Kogi BBQ consists of two Kogi Korean taco trucks that roam the streets of L.A. selling their tasty tacos. The only way to find out where the trucks are headed next is through their Twitter feed, which you can find on their website at http://www.kogibbq.com/. If you're not familiar with Twitter, in their own words, it is "a service for friends, family, and co-workers to communicate and stay connected through the exchange of quick, frequent answers to one simple question: What are you doing?" For more info go to http://www.twitter.com/.
Apparently, these tacos are quite the rave! People are so into this that by the time the trucks arrive at their next destination, there is already a line of people waiting! The best part is that not only is the food supposed to be delicious, but it is inexpensive, with tacos at about $2! So, if you've never chased a taco truck around L.A., you may want to consider it.
