The butcher shop that used to be called 'Haseonsaeng' and did wet-aging has been renovated and finally became Kann, after being Hann.

Haseonsaeng's second branch also seems to have changed to something like King's Meat, and while I don't know the inside story, it's a butcher shop, so you can just pick your meat and pay for the table setting fee.

The downside is that they only accept cash or G-cash.
