Aloha, kimchi! First came the taco trucks: parked in unsuspecting neighborhood nooks in the Pacific Northwest, these four-wheeled eateries were the king of $1 tacos and tall glasses of milky horchata that, in my opinion, doubled as dessert. Not surprisingly, great ideas spawn competition, and innovation. The latest truck in the region is the Marination Mobile, inspired by Los Angeles's Kogi barbecue truck, and an itinerant home to tortillas served with a Korean and Hawaiian twist. Kalbi tacos? Check. Shredded kahlua pork sliders? You got it. Spam musubi? It wouldn't be Hawaiian without it. With a Twitter feed to let hungry customers know its whereabouts, the Marination Mobile has already gained plenty of fans, who note that if the food isn't spicy enough for your tastes, a bottle of Sriracha chile sauce stands at the ready.
