My business colleague and I were looking for an authentic place to eat while in Koreatown, Los Angeles and Oo-Kook was highly recommended by a gentleman who had spent many years in Korea, and now works in Koreatown. We walked about 5 minutes from our hotel (the Line) to what was obviously a neighborhood favorite. While we we seated right away, we were not the only ones ready to eat at 7pm on a Tuesday! The crowd (which grew significantly by the time we left) was a mix of young professionals, 30ish men out for a night of food and friends, and (many) families with young children as well as with teens. The back room where we were seated was much louder than the front where the many families were seated, but not annoyingly so. The food is all you can eat for about $27. The menu gives about 28 choices from the typical beef, pork, chicken, seafood (shrimp and octopus) and vegetables, to some choices for the more adventurous, including beef tongue and, yes, intestine (nope, didn't try that!) There were accompanying side dishes of spicy radish, jalapeños, cabbage, and so on, as well as steamed rice and a beautiful green salad. The meats are brought out to be cooked by you on a grill at the table. The INCREDIBLY attentive and good humored waiter helped these two novices navigate the cooking process as well as the meat selection. We enjoyed the marinated selections best, though all were very good! Try numbers 2, 7 and 11 if you love beef! Excellent food, no limit to what or how much you want to try, and no rush to get you to finish. The cooking process is up to you, so no complaints of done too much or too little, or that it isn't hot enough! Drink selections are limited to some soft drinks, beer and a very yummy vodka called sojo. The atmosphere is fun and laid back, the food is delicious, and the wait staff attentive and, forgiving of (and so helpful for) our lack of knowledge! We had a fabulous time eating delicious food in a truly non-tourist venue! We will recommend this
