For the price I paid and considering that it is in the core downtown area, I think this place is pretty good. I would go back again, especially with the limited options for Korean food options downtown. They even do tofu bulgogi! I was super excited to find that.
As for seating, be prepared to not have a seat. There are a few bar stools as well as 2 very narrow tables which are 2-seaters each basically. The shop isn't very big so you might feel a bit cramped. It's great in the summer when you can just buy and take it away since there are small parks nearby where you can sit and enjoy your food. Or if you want to just go out for a walk to get lunch and go back to your desk to eat it, that's an option too. Your meal includes a free miso (self serve station) soup.
