When it comes to Korean food, I'm really not hard to please, so I throw 5 stars at them if they meet the major points: food, service, atmosphere.
I was with a group of 8, some of which were Korean food virgins. Everyone was really happy with their meals. I ordered the japchae (which was exciting because it isn't always served as a main dish) and while it was a little saucier than some I've had, it was still tasty as heck. We ordered a bunch of appetizers to share and they were all very good. The seafood pancakes were off the hizzay.
The waiting staff were very friendly - our waitress was patient with me when I attempted to order in Korean :) We over-ordered bottles of soju, so I was pleasantly surprised they took one back. Some places wouldn't do that, I'm sure.
And the atmosphere was very clean and tidy. You gotta love the screen of k-pop videos too. Great dinner conversation piece :)
