I've dined here with friends for dinner a couple times and we all enjoyed our dining experience. Both times, It wasn't too packed so it was a nice, casual atmosphere. The interior was clean and on the hip side perfect for groups. The service is also friendly and attentive.
The menu has a nice variety options and we ordered a bunch to try. From appetizers, drinks and freshly prepared meats and veggies. Everything was tasty and were of good quality, nothing disappointed our taste buds.
I highly recommend Gangnam if you're in need to try a new spot off-strip.
*note: If you give a good yelp review on the spot, you'll get a free dessert. It's not something I'm crazy about giving an instant review for, but if you really like dessert, it's there.
