True to its name, this food truck combines two of my favorite things: the streets and the meats. Julia Yoon (the owner and mastermind) doesn't stay in any one place too long, but you can find her route on her Web site. Once you do find her, though, you won't be disappointed. For six bucks by far the cheapest Korean on my list you get a meat dish with rice and japchae (a vegetable and noodle dish). You can opt for the kimchi fried rice, one of the best things I've ever tasted. The food is made fresh to order when not driving, Julia and her assistant are cooking up the goods, which makes Seoul on Wheels truly a movable feast worth finding.
