If you want to invite people to taste authentic Korean-style food, you still want some grades.

I suggest you go to Renfeng Pavilion, a shop opened by North Koreans in Changchun. The chefs are all North Koreans who eat in private rooms and sing Korean songs for free, but they don't charge tips or sing.

The location is opposite to Fat Niu in China City, West Chaoyang Road.

The average store eats good real food at Qingming Street/Koryo Dynasty on the way to the airport on Xi 'an Road.

They are eating at their own homes.
