The food deserves five stars, the service two - I'm averaging. Gangnam does not take reservations. The average wait time for dinner is 30 min if you come with a group, it might be shorter for a couple. We ordered a variety of meats, drinks and rice. The food came out super fast. All of the meats were beautifully marinated and we enjoyed grilling them to perfection. We would've ordered more food and would've had another round of drinks and would redeem our Yelp desert offer if we weren't given a check while we were still eating. After the food arrived we could not get anyone's attention for more drinks and more rice. Finally, I caught one of the guys that was running by and asked for what we needed. Got the rice, not the drinks... Our experience was short and largely unsatisfactory since we felt rushed watching all the staff constantly running by, but seemingly not stopping anywhere.
