LA Times has a great profile on Kogi a mobile restaurant featuring a Korean BBQ taco truck that travels around Los Angeles announcing their location via Twitter. The truck has become a huge sensation, generating long lines where ever it shows up. NPR recently did a story on the Kogi trucks as well.
The truck and its staff of merry makers have become a sort of roving party, bringing people to neighborhoods they might not normally go to, and allowing for interactions with strangers they might not otherwise talk to. A constant Twitter feed connects truck-followers and updates them about whether Kogi is going to be late to its next stop. Occasionally, a negative Nelly will rain on this love parade by asking the Kogi truck to park elsewhere; when this happens, legions of Kogi-lytes rally to find a desirable new location.
