This episode visits New York and Los Angeles - home to the two largest Korean populations in the United States - to explore what distinguishes each. Both are 24-hour hubs of food and drinking culture. However, New York City's Koreatown covers just one block, whereas Los Angeles' Koreatown seems like a city unto itself. At dinner with Lisa Ling and her husband Paul Song, chef Sang Yoon breaks down the basics of Korean cooking. Back in New York, at Saveur Magazine'stest kitchen, Top Chefwinner Kristen Kish, a Seoul-born Korean adoptee, receives her first-ever Korean cooking lesson, a kimchi tutorial, from Korean homemaker and YouTube sensation, Maangchi. The episode ends with a night out at Pocha 32, an export of Korea's popular "tent" restaurants.
