As a missionary, I went to Seoul several times. But it was only to go to the international hospital there (you'll need to click this link to understand about Severance). Since I arrived in Korea, I've been anxious to get to Seoul and go to the temple, as well as explore a little bit. Unfortunately I forgot to take pictures most of the weekend. I suppose that means I'll just have to go back soon!
Here is the restaurant link.
