I visited there twice, and I enjoyed the experience both times.
Their BBQ is delicious, and the owner's son comes around to make sure we are having a great time there :)
And I like the atmosphere, too; feels quite authentic.
The only down side of it is the menu. If you cannot read Korean, it is hard to follow (and it is rather big). Luckily, I went both times with my Korean friend, who knew what to order.
