Had a few inquiries on where this is...
It's off Yanghwa-ro, as you're turning towards Red Road. If you see a Mega Coffee, then a Kyochon Chicken on your right... Look left. Doshi is in Hangul but Anna is in English. There will be a lot of people standing in front of the chicken spot, it's pretty popular. If you have a chance, you should eat there too, its good! I just wish the wait was an hour instead of 30 minutes
It's been here for a while. I stopped in a few years ago and they told me they were closed. I don't know if it's because I was a foreigner or because it was like 10 am. Either way, I'm always curious, so I gave it another shot. This was my first time getting service.
