I usually cringe at the cost of a restaurant where you cook your own food but Gangnam is surprisingly affordable, especially if you take my advice and order the combos for your group. The menu says they are for 2 people but we had a group of 4 and the combo filled us all. You can always add one or two items a la carte if you are still hungry.
The meat is surprisingly well marbled and tender and fresh. The sauces are perfect compliments to the meet.
I thought the salad was a little bit of an afterthought as it was mostly lettuce but we still ate it.
Our favorite was the bulgogi bibambap.
The service felt a little off as they had a difficult time understanding and we were very conscious that they were watching us the whole time. I understand it is your job to clear our table as we finish a plate but there are ways to be less intrusive about it. Also, they were fixing a light in the restaurant while we were all there. Still, this place is very enjoyable and reasonably priced.
