When a food truck parked on a nondescript Emeryville block on a random Tuesday afternoon has a line extending down the sidewalk twenty feet, you have to suspect something's up. And when you have to wait fifteen minutes to order a pre-made foil-wrapped burrito, that better be one heck of a burrito. Well, it is and it isn't — it's warm and delicious and wonderful, but it's not exactly a burrito. It's Seoul on Wheels' korrito — a Korean burrito, featuring spicy rice, kimchi, cheese, cilantro, sour cream, and your choice of filling: chicken, spicy pork, tofu, or bulgogi (Korean rib-eye beef). The taste is like nothing you've ever had before: sweet, saucy, spicy, tangy, cheesy, gooey. For the complete Korean burrito, go with the bulgogi; its soft, lightly crunchy texture stands out ever so subtly from its surroundings, and its traditional barbecued flavor feels right at home in a tortilla. The result is a new height in cross-cultural comfort food.
