Spicy Chicken Sandwich...a bit too expensive (around 12,000), but the fries are good. I recommend his taco and burrito offerings.
It's a parking lot that has been converted into a dance club. The owner Johnny was the guy who used to drive around in that big old yellow taco truck. He's gone inside now. There is a great take-out place up by Hannam and there is a new joint next to B(one) in Itaewon.
Good food, at decent prices. I recommend his burgers and his cobb salad sandwich.
