I only went once with friends, but the Espresso Bingsu (shaved ice) was great. It was a tirimisu in shaved ice form, it didn't come out frozen. There was a shot of espresso to pour into the bingsu. The bingsu was soft, no chunks of ice in it. There were lady fingers and cheesecake bits (they were larger than the size of their tony spoons) in addition to their shaved ice.
There weren't that many people inside when we went on a Saturday night, but it might also be because it's fairly new. It's pretty dark with music, but that's you would expect from a bar. But the hanging wood pieces looked really low, even for someone who's 5'3.
My only real complaint would be the price of the bingsu. After tax, a little over $10. It was good but it was a little overpriced.
