Came here for lunch on a Saturday and it was decently packed. My group ordered the Spicy Pork Bulgogi and Spicy Chicken Bibimbap to share. We also ordered a Kids' Combo for a child in our group. Overall, the food here is really good, as the meat is perfect marinated. Since we only ordered one portion of KBBQ, they cooked it for us and brought it out. Everything from the banchan to the main dishes were fresh and flavourful. I deducted one star for what seemed to be often miscommunication with the servers. For instance, when we were asked what we would like to drink, they were told that everyone wanted tea. The server then proceeded to bring out water for some reason. Also, the kid wanted orange juice (which came complimentary with the Kids' Combo) but the server brought out apple juice. It was just a few inconsistencies that resulted in the 4/5 rating.
In terms of ambiance, the restaurant is very sleek and modern. They used traditional cues yet executed it in a modern way. I really enjoyed the restaurant, as it felt very upscale and luxurious. This should be expected however, since the price here seems a little higher than other places.
P.S.: They give out free Haagen Daz ice cream with a Yelp check in. The man said I had to post a review first but I clarified with him that the offer was with check in only, so he shouldn't make customers obligated to review.
