Supposedly, Jian BBQ has great food. I wouldn't know. I never actually got to eat there. I had the worst customer service I've ever experienced in a restaurant and left before we actually ordered. In my defense, I did try to order several times. But it just didn't work out. More to come in a bit.
Meanwhile, if you're looking for a good Korean barbecue restaurant in Los Angeles, there are several.
A personal favorite is Road to Seoul, an all-you-can-eat joint down on Western and Pico. For the bargain price of $16.99, you get all the panchan you want, including kimchi pancake, plus a nice selection of meats (ranging from the traditional galbi and bulgogi to sirloin, brisket, chicken, even baby octopus). The food is fantastic, rivaling the quality at many of the non-AYCE places, and the wait staff is extremely friendly. So if you're thinking about Jian BBQ, do yourself a favor and go to Road to Seoul instead.
