Korean barbecue tacos, from 9 PM to midnight tonight.
UPDATE 11:30 PM: The never-fails-to-amaze Bill Westphal gives us an on-the-scene report of Kogi:
It was not as crowded as the Grilled Cheese Truck. Lynne and I actually waited in line and sampled a couple of different things off of the menu. It was good and worth the wait.We need to see more of the Kogi and Grilled Cheese Trucks in Altadena.
