How’s this for social media at work? The latest twist on L.A. fusion is the Kogi Korean BBQ taco truck. Every night, the Kogi truck parks in a new location and its ardent followers find it via Twitter updates. Even for Angelenos who are used to excellent Korean and Mexican food, this has become a word-of-mouth sensation. There’s certainly no other place that I know of to get Korean BBQ on a taco. Hundreds are following the tweets, overtaking the hordes we’re used to seeing at Pink’s Hot Dogs. Still, it may be worth the wait (and signing up for Twitter) for this unique flavor excursion.
