Recently we went to the Koreatown Plaza in Los Angeles. We love going there for their food court. It's kid-friendly and you have an array of different Korean foods, even non-Korean such as Sushi and Pho. We also like the fact that it's relatively affordable.
Usually any city with a big Korean population will have some type of Korean food court. It's a great way to try different Korean foods without breaking the bank. The hard part is figuring out which one to order.
